蒋孝鹏摘There are various structural planes in rock mass,which will affect the physical and mechanical properties of rock mass,weaken the mechanical properties of rock mass and reduce its stability.Therefore,the deformation and strength prop erties of structural plane play an important role in engineering practice.Firstly,the regular zigzag structural plane is selected from a variety of structural surfaces.Then the design of the direct-shear test was started:samples were made from concrete and gypsum to simulate the rock mass.In order to further study the shear strength and other properties of the structural plane,the shear tests of the miscellaneous and single structural surfaces are carried out by using the hydraulic direct shearing appara tus and according to the operation steps.
Key words:rock mass regular zigzag structural plane direct-shear test
