一、前言岩土边坡的稳定性分析,需要测定岩土的力学参数,而抗剪强度是其最重要的参数.根据栗木锡矿老虎头边坡研究总体规划,初步把老虎头边坡体分成五个区,其第四区稳定性差属不稳定区,此区内的岩土主要是夹有砂岩块的残坡积土。测定残坡积土的抗剪强度有两种方法:一是常规土的小试样测定方法,二是粗粒土大面积直剪方法.栗木锡矿老虎头边坡的试
I. INTRODUCTION The stability analysis of geotechnical slopes requires the determination of the mechanical parameters of rock and soil, and the shear strength is the most important parameter. According to the overall plan of the tiger head slope research in Limu tin mine, the tiger head slope body is initially Divided into five areas, the stability of the fourth area is unstable, and the rock and soil in this area is mainly the residual slope with sandstone blocks. There are two methods to determine the shear strength of residual slopes: one is the determination of small samples of conventional soil, and the other is the large-area direct shear method of coarse-grained soil.
