动力荷载作用下软粘土的残余变形计算模式

A Model for Predicting the Cyclic Behaviour of Soft Clay

在试验结果的基础上，提出了动力荷载作用下计算软粘土残余变形的模式。并将计算结果与不排水和部分排水情况下观测到的孔隙水压力及残余应变进行比较，两者具有较好的吻合性。本文所提出的计算模式可用来估算动力荷载（例如地震荷载、交通荷载）作用下建于软粘土地基上的建筑物及其它设施所产生的附加沉降。

Based on the results of cyclic triaxial tests on the reconstituted ariake clay, a empirical model ispresented for predicting the cyclic behaviour of soft clay. The results of analyzing the behaviour of clay during patially drained conditions were compared with the observed values of pore pressure and shear strains inundrained and partially drained cyclic triaxial tests. It is suggested that the proposed model constitutes;lpractical tool for evaluating the settlements and stability of foundations on clay under partially drained cyclicloading.
