RB模式下挡土墙主动土压力强度的计算研究
The study on active earth pressure against rigid retaining wall rotating about the base
摘要
Abstract
Based on the Coulomb 's theory of active earth pressure and progressive rupture mechanism in the backfill,the wall movement and the associated mobilization of internal friction angles and wall friction angles were considered in a new simplified manner,a modified active earth pressure method was presented.The effect of the distributions of the mobilized internal friction angles and the mobilized wall friction angles which vary with depth on the distribution of earth pressure was discussed by a simulation example.In addition,the effect of the Derivative of the mobilized internal friction angles and the mobilized wall friction angles with respect to depth on the distribution of earth pressure was discussed.Comparisons of results by the proposed method with observations from model tests and other methods show that the method can provide a good prediction of lateral pressures for walls rotating about the base when proper distributions and the Derivative of the mobilized internal friction angles and the mobilized wall friction angles with respect to depth are used.关键词
