摘要

对汉口某地的淤泥质粘土进行了一系列应力路径试验。试验表明，饱和软粘土的应力应变性状与应力路径密切相关，在各种减P应力路径下的应力比与轴应变之间均存在着良好的双曲线关系，据此，建立了一个和应力路径有关的归一化应力应变双曲线模型。分析了排水试验中的体变特性和不排水试验下的孔压变化特性。

Abstract

A series of stress path tests are carried out for undisturbed mucky clay samples from Hankou. The tests results indicate that there is a good hyperbolic connection between the axial strain and stress ratio R in those decreasing p path tests

then a normalized hyperbolic model of stress-strain is proposed for soils which undergo decreasing p path. Volume change behavior in drained tests and pore pressure characteristics in undrained tests are also described.
