| Abstract: | Based on the comparison of the results and methods of in-situ direct shear test and direct shear test in a laboratory,the advantages of in-situ direct shear test are expounded and the problems existed in the direct shear test in the laboratory are discussed.It is proved that the in-situ direct shear test method can be widely used in exploration of mine slopes.The testing results of soil shear strength in saturation condition and natural condition show that pore water pressure has a big influence on stability of slopes. |
