| 摘 要： | 软粘土的流变特性已逐步被人们所认识和重视 ,且有重大的工程意义。笔者选择二种典型的软粘土进行室内流变试验 ,从而对二种软粘土———淤泥质粘土和粉质粘土的长期剪切模量进行研究和分析 ,提出了一些新的见解 ,认为土体剪切模量与应力间呈抛物线关系 ,与时间负幂指数关系 ,最终趋于一稳定值即长期剪切模量Ms.

| Abstract: | The sheological characteristics of soft soils was secognized and has gradually teen taken attention to.This index has great significance in engineering practice.In this paper,two kinds of typical soft soil,macky and silty clay were chosen for sheological tests to investigate their long-tesm shear modulus.Some opinions are presented.That tells us the shear modulus has a pas abolic selation to stsess and has megative powen exponant selation to time qinal ly if becomes a constant,the long-tesm thear modulus. |

| Keywords: | soft soil long-tesm shear modulus stsess and time in fluence |
