ABSTRACT

Joint plane, if loaded in two directions with normal stress and shear stress, will arise one or several different directions of deformation, which exhibits as the closure and slippage deformation. Studies on slope reinforcement methods are important for geotechnical engineering. All of the reinforcement methods can be divided into two groups, the passive reinforcement methods and the active reinforcement method. Cement grouting constitutes one of the major techniques used for stabilization in civil engineering. It is widely applied in tunnel engineering. It consists in injecting into the rock mass a cement grout mixture under controlled pressures and volumes. Macroscopic effect of rock slope is simulated by three dimensions explicit finite difference code, FLAC3D. Models for jointed slope are divided into two groups: before grouting and after grouting.
