Wedge Size Issues on Calculating Seismically Induced Lateral Earth Pressure for Retaining Structures-An Overview and a New Simple Approach
並列摘要
Case history data and data from recent experiments indicate that currently used methods for evaluating seismically induced lateral earth pressure are conservative and can potentially lead to overdesign. This paper reviews commonly used methods (e.g., Mononobe-Okabe, M-O, method) and discusses wedge size issues in the calculation of seismically induced lateral earth pressures for retaining structures. Unlike the M-O method, wherein the critical wedge is dependent on seismic intensity, a fixed-wedge approach is proposed in this study on the basis of observations from case histories, experiments, and FEM analysis results. The earth pressures calculated by the proposed procedure agree well with recent experiments. Hence, the fixed-wedge approach is recommended in lieu of the M-O method.
