摘　　要：国内外对软粘土的震陷与计算分析还不多 ,我国建筑抗震设计规范也尚未评价软粘土的震陷问题及规定其抗震措施。根据某高速公路建设的需要 ,研究了软粘土在循环荷载作用下的动力特性和计算模拟方法 ,进行了震陷估算及抗震措施评价 ,得到了一些新的认识与结论 。Seismic settlement analysis of soft clay has been studied little at home and abroad.Our building aseismic design criterion has not judged seismic settlement of soft clay and defined relevant aseismic means.Based on the construction demands of a certain freeway,the dynamic characteristics and computation method of soft clay under cyclic loading are investigated,and estimation of seismic settlement and evaluation of aseismic means are carried. Some new realization and findings are obtained, which can be referred in other softclay areas with frequent earthquake.
