摘要

基于对建筑物不均匀震陷机理的新认识,借助分层总和原理,基于不规则荷载下土的残余应变模型及土体逐步软化模型,提出了一套建筑物不均匀震陷的简化分析方法。此方法较以往更合理地考虑了土、结构和地震动的共同效应,可实现对不均匀震陷的时程分析,且原理简单,方便工程应用。方法的可靠性通过大型振动台实验进行了检验。
Based on the mechanism of earthquakeinduced differential settlements of buildings, the layerwise summation method, the model of residual strain of soil, under irregular loading and the progressively softened model, a simplified analytical method for estimating the earthquakeinduced differential settlement of buildings are presented. The simplified method can consider the combined effect of the soil, structure and ground motion more reasonably and can describe the process of the differential settlements of the buildings. The comparison results with large shaking table tests indicate that the new simplified method is reliable. 
