  • Site specific ground motion simulation and seismic response analysis for microzonation of Kolkata
    Narayan Roy and R.B. Sahu
    Abstract; Full Text (816K)

The spatial variation of ground motion in Kolkata Metropolitan District (KMD) has been estimated by generating synthetic ground motion considering the point source model coupled with site response analysis. The most vulnerable source was identified from regional seismotectonic map for an area of about 350 km radius around Kolkata. The rock level acceleration time histories at 121 borehole locations in Kolkata for the vulnerable source, Eocene Hinge Zone, due to maximum credible earthquake (MCE) moment magnitude 6.2 were generated by synthetic ground motion model. Soil investigation data of 121 boreholes were collected from the report of Soil Data Bank Project, Jadavpur University, Kolkata. Surface level ground motion parameters were determined using SHAKE2000 software. The results are presented in the form of peak ground acceleration (PGA) at rock level and ground surface, amplification factor, and the response spectra at the ground surface for frequency 1.5 Hz, 3 Hz, 5 Hz and 10 Hz and 5% damping ratio. Site response study shows higher PGA in comparison with rock level acceleration. Maximum amplification in some portion in KMD area is found to be as high as 3.0 times compared to rock level.

Key Words
synthetic ground motion; site response; time history; PGA; response spectra; amplification.

  • Analytical solution for undrained plane strain expansion of a cylindrical cavity in modified cam clay
    Vincenzo Silvestri and Ghassan Abou-Samra
    Abstract; Full Text (1163K)

This paper presents the results of analytical and numerical analyses of the effects of performing a pressuremeter test or driving a pile in clay. The geometry of the problem has been simplified by the assumptions of plane strain and axial symmetry. Pressuremeter testing or installation of driven piles has been modelled as an undrained expansion of a cylindrical cavity. Stresses, pore water pressures, and deformations are found by assuming that the clay behaves like normally consolidated modified Cam clay. Closed-form solutions are obtained which allow the determination of the principal effective stresses and the strains around the cavity. The analysis which indicates that the intermediate principal stress at critical state is not equal to the mean of the other two principal stresses, except when the clay is initially isotropically consolidated, also permits finding the limit expansion and excess pore water pressures by means of the Almansi finite strain approach. Results are compared with published data which were determined using finite element and finite difference methods.

Key Words
undrained cylindrical expansion; plane strain; modified Cam clay; stress-strain curves; analytical and numerical analyses; comparisons.

  • Numerical validation of Multiplex Acceleration Model for earthquake induced landslides
    Lu Zheng*, Guangqi Chen, Kouki Zen and Kiyonobu Kasama
    Abstract; Full Text (1195K)

Due to strong ground motion of earthquake, the material in the landslide can travel a significant distance from the source. A new landslide model called Multiplex Acceleration Model (MAM) has been proposed to interpret the mechanism of long run-out movement of this type of landslide, considering earthquake behaviors on slope and landslide materials. In previous study, this model was verified by a shaking table test. However, there is a scale limitation of shaking table test to investigate MAM in detail. Thus, numerical simulation was carried out in this study to validate MAM under full scale. A huge rock ejected and A truck threw upwards by seismic force during Wenchuan Earthquake (Ms. 8.0) was discussed based on the simulation results. The results indicate that collisions in P-phase of earthquake and trampoline effect are important behaviors to interpret the mechanism of long run-out and high velocity. The results show that MAM is acceptable and applicable.

Key Words
long run-out landslides; earthquake; Multiplex Acceleration Model; trampoline effect; UDEC

  • Effect of suction on volume change and shear behaviour of an overconsolidated unsaturated silty soil
    A.R. Estabragh and A.A. Javadi
    Abstract; Full Text (794K)

This paper presents the results of an experimental study on the effect of suction on compressibility and shear behaviour of unsaturated silty soil under various types of loading. A series of laboratory experiments were conducted in a double-walled triaxial cell on samples of a compacted silty soil. In the experiments the soil samples were subjected to isotropic consolidation followed by unloading and subsequent reloading under constant suction and prescribed overconsolidated ratio. The experimental results are presented in the context of an elasto-plastic model for unsaturated soil. The effects of suction on mechanical behaviour of unsaturated silty soil are presented and discussed. It is shown that increasing suction affects the shear behaviour of unsaturated soils, but there is a limit beyond which, further increase in suction will not result in any significant change in the behaviour.

Key Words
unsaturated soil; suction; overconsolidation ratio; triaxial cell

  • Settlement analysis of viscoelastic foundation under vertical line load using a fractional Kelvin-Voigt model
    Hong-Hu Zhu, Lin-Chao Liu, Hua-Fu Pei and Bin Shi
    Abstract; Full Text (889K)

Soil foundations exhibit significant creeping deformation, which may result in excessive settlement and failure of superstructures. Based on the theory of viscoelasticity and fractional calculus, a fractional Kelvin-Voigt model is proposed to account for the time-dependent behavior of soil foundation under vertical line load. Analytical solution of settlements in the foundation was derived using Laplace transforms. The influence of the model parameters on the time-dependent settlement is studied through a parametric study. Results indicate that the settlement-time relationship can be accurately captured by varying values of the fractional order of differential operator and the coefficient of viscosity. In comparison with the classical Kelvin-Voigt model, the fractional model can provide a more accurate prediction of long-term settlements of soil foundation. The determination of influential distance also affects the calculation of settlements.

Key Words
soil foundation; fractional viscoelastic model; the Flamant-Boussinesq solution; settlement; Laplace transform

    Research and Publication Ethics

    All the editors, publishers, researchers, and peer reviewers of Techno-Press journals strongly encourage to carefully review and follow the Committee on Publication Ethics (COPE) guidelines:

    1. Authorship
    Authorship credit should be based on
        (1) Substantial contributors to the conception or design of the work or the acquisition, analysis
       or interpretation of data for the work,
        (2) Drafting the work or revising it critically for important intellectual content,
        (3) Final approval of the version to be published, and
        (4) Agreement to be accountable for all aspects of the work in ensuring that questions related
       to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
    Authors should meet these four conditions after the initial submission of a manuscript and any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. This letter must be signed by all authors on the paper. Techno-Press does not correct authorship after the final acceptance unless a mistake has been made by the editorial staff. Authorship may be changed before the final acceptance when the authorship correction is requested by all of the authors involved with the manuscript. The corresponding author takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process. The corresponding author should be available throughout the submission and peer review process to respond to editorial queries in a timely manner, and should be available to respond to critiques of the work and cooperate with any requests from the journal for data or additional information or questions about the paper even after publication.

    2. Originality, plagiarism and duplicate publication
    Submitted manuscripts must not have been previously published or be under consideration for publication elsewhere. No part of the accepted manuscript should be duplicated in any other journal without the permission of the Editorial Board. Submitted manuscripts are checked for possible plagiarism or duplicate publication upon the paper's arrival. If plagiarism or duplicate publication is detected, the manuscripts may be rejected, the authors will be announced in the journal, and their institutions will be informed. There will also be penalties for the authors. A letter of permission is required for any and all material that has been published previously. It is the responsibility of the author to request permission from the publisher for any material that is being reproduced. This requirement applies to text, figures, and tables.

    3. Conflict of interest statement
    The corresponding author must inform the editor of any potential conflicts of interest that could influence the authors' interpretation of the data. Examples of potential conflicts of interest are financial support from or connections to companies, political pressure from interest groups, and academically related issues. In particular, all sources of funding applicable to the study should be explicitly stated.

    4. Process for managing research and publication misconduct
    When the journal faces suspected cases of research and publication misconduct, such as redundant publication, plagiarism, fraudulent or fabricated data, changes in authorship, undisclosed conflict of interest, ethical problems with a submitted manuscript, appropriation by a reviewer of an author's idea or data, and complaints against editors, the resolution process will follow the flowchart provided by COPE,
    The discussion and decision on the suspected cases are carried out by the Editorial Board.

    5. Editorial responsibilities
    The Editorial Board will continuously work to monitor and safeguard publication ethics:
    * Guidelines for retracting articles;
    * Maintenance of the integrity of academic records;
    * Preclusion of business needs from compromising intellectual and ethical standards;
    * Publishing corrections, clarifications, retractions, and apologies when needed; and
    * Excluding plagiarized and fraudulent data.
    The editors maintain the following responsibilities:
    * Responsibility and authority to reject and accept articles;
    * Avoid any conflict of interest with respect to articles they reject or accept;
    * Promote the publication of corrections or retractions when errors are found; and
    * Preserve the anonymity of reviewers.
