摘要
循环荷载作用下饱和软粘土中孔压的变化是研究饱和软粘土循环特性的重要特性之一。本文通过对杭州市正常固结饱和软粘土进行的大量试验 ,研究了影响循环荷载作用下饱和软粘土孔压变化的主要因素。已有的孔压模型大多数均直接建立孔压与应变的关系 ,而各影响因素下孔压与应变关系不唯一 ,本文在试验的基础上 ,提出了正确反映这些影响因素的孔压模型 。
The variation of pore pressure in saturated soft clay under circulating load is a major topic in the study of circulating features of saturated soft clay. The m ain factors which influence the variation of pore pressure in saturated softclay under circulating load are discussed through large amount of tests on norm al consolidated saturated soft clay in Hangzhou city.Most of the existing pore pressure models are established directly on the relationship of pore pressure and strain which are not unique under different influential factors. pore pressure models which reflect those influential factors accurately are proposed in this paper and model parameters are also determ ined.
