Taylor's Slope Stability Chart For Combined Effects Of Horizontal And Vertical Seismic Coefficients, Pragyan Sahoo, Sanjay Kumar Shukla
Research outputs 2014 to 2021
Design standards and codes of practice on earth slope stability often recommend the pseudo-static method of analysis for determining the factor of safety of a slope subjected to seismic forces. In most pseudo-static methods of analysis, the horizontal seismic force is considered without due weightage to vertical seismic force. In the past, Taylor's stability chart for a homogeneous cohesive-frictional soil slope has been extended to consider the effect of horizontal seismic force only. In this paper, an attempt is made to develop an analytical formulation considering both horizontal and vertical seismic forces in order to estimate the factor of safety …
Earthquake Load Attenuation Using Eps Geofoam Buffers In Rigid Wall Applications, Richard J. Bathurst, S Zarnani
Earthquake Load Attenuation Using Eps Geofoam Buffers In Rigid Wall Applications, Richard J. Bathurst, S Zarnani
Research outputs 2013
The paper is a synthesis of previously published work by the authors that is focused on the use of expanded polystyrene (EPS) geofoam buffers for seismic load attenuation against rigid basement and soil retaining walls. The paper begins with a brief description of the first documented field application followed by a description of physical 1 m-high reduced-scale shaking table tests that provided the first "proof of concept". Next, details of the development and verification of a displacement-based model and a FLAC numerical model are described and simulation results that were verified against the physical shaking table tests presented. The numerical …
