Abstract
Various methods are available to estimate seismic earth pressures on soil retaining structures which cane be grouped to experimental, analytical and numerical methods. 1G model shaking table studies or high-g level centrifuge model shaking studies give some insight on the variation of seismic earth pressures along height of the retaining structure. In the simple analytical methods, M-O method based pseudo-static analysis is extensively used to evaluate seismic earth pressure variation and its probable resultant location. Pseudodynamic analysis method based analyses are also developed and are in progress for the same. Besides, these experimental and analytical methods, FEM or FDM based numerical simulations of the retaining structures provide much information on the seismic lateral earth pressure variation. In this paper, the methods available and the procedures to be followed to determine the lateral seismic earth pressures and their recent developments are summarized. Numerical simulations of seismic behavior of cantilever retaining walls was performed using FLAC and the results obtained regarding seismic earth pressures are discussed.
