刚性挡墙绕底部转动模式下有限土体非极限状态地震土压力
Non-limit State Seismic Earth Pressure for Limited Soil Under Rigid Retaining Wall Rotation Around the Bottom
摘要
Abstract
To investigate the variation of seismic earth pressure in limited soil under the rigid retaining wall base rotation(RB)mode at non-limit state,a seismic earth pressure calculation formula was derived based on the horizontal differential unit method and the pseudo-dynamic method.The corresponding numerical algorithm was also established.Example analysis shows that the seismic active earth pressure in limited soil exhibits periodic characteristics with time and nonlinear variations with depth,and the calculation results are in good agreement with the results of shaking table tests.Parameter analysis indicates that the seismic earth pressure decreases significantly with the increase of initial internal friction angle,wall base displacement ratio,and the decrease of seismic acceleration coefficient.The total seismic earth pressure is primarily influenced by the initial internal friction angle and wall base displacement ratio,while the seismic acceleration coefficient mainly affects the magnitude of the resultant force.It is shown that the seismic design adopting only the pseudo-static method tends to be unsafe under strong earthquake conditions.This method offers valuable theoretical insights for the seismic design of retaining structures in practical engineering applications.关键词
