摘要通过对粉性土这种特殊土用作高等级公路底基层，进行稳定方法研究，寻找一种力学性能和路用性能都适宜的稳定类型，从而为广大使用者提供参考。
The basic physical and mechanical properties , mineral composition , micro structures , swelling potential , consolidated drained triaxial shear strength , parameters of constitutive model and residual strength of the soft clayey rocks were tested in laboratory with a large number of natural samples . the changing trend of the strength about these rocks is obtained by modeling the condition of softening due to immersion . from the principles of modern soil mechanics , the structural and swelling characteristics of soft clayey rocks were analyzed systematically
本文通过现场调查，查明风化泥质软岩的宏观结构特征，利用现代试验测试手段，取原状土系统进行特殊土室内土工试验，测定土的基本物理力学特性、矿物成分及微观结构、膨胀性、三轴排水剪强度及本构模型参数、软化残余强度，并模拟土体在长期浸水软化后的强度变化趋势，测试该类土的浸水软化残余强度。
