... the inner cohesion of the material, in the middle of the eighteenth century. It was expounded that the friction caused by the normal stress on the slipping plane should be taken into account besides cohesion in Mohr-Coulomb's strength theory. In twentieth century, many scholars such as Drucker, Bishop...

... stress can be calculated at different given normal stress, generating a series of shear stress and normal stress, and the values of cohesion and friction were determined via linear regression analysis. Then take the research on shear strength of rock mass from China-Myanmar Oil and Gas Pipelines...

... be used to represent the potential strength to some degree. The bigger the summit uniaxial compressive strength, the bigger the potential compressive strength. Generally, for shearing failure, the summit cohesion and friction angle are used to describe the potential strength. The creep process can...
