坡残积粘性土在我国不仅分布较广,而且往往与斜坡(或边坡)的稳定性有密切关系。因此对这种土体抗剪强度的研究是岩土工程的一个重要课题。本文主要是以川西绵阳地区的坡残积粘性土为例,通过多年的工程实践,对坡残积粘性土不同抗剪强度试验方法(室内和野外)的成果进行了分析对比。 The residual clay in the slope is not only widely distributed in China, but also has a close relationship with the stability of the slope (or slope). Therefore, the study of the shear strength of this soil is an important issue in geotechnical engineering. In this paper, the residual clay soil in the Mianyang area of ​​western Sichuan is used as an example. Through years of engineering practice, the results of different shear strength test methods (indoor and outdoor) of cohesive soil on the slope have been analyzed and compared.
