%X The propagation and coalescence mechanism of closed joints under uniaxial and biaxial compressive stress is studied by rock-like material model tests. 8-node singular isoparametric element mode is applied to simulate the stress field near crack tip. Both the numerical and experimental results of crack propagation are in consistence. The new results are useful to study mechanical properties of jointed rock mass. Furthermore, based on the laboratory test results of KIC, the propagation area of fractures in surrounding rock mass of pump stations of Shanxi Yellow River Diversion Project during excavation and support is obtained.
