Abstract：There are often water or soft in joints of rock masses. It is an important problem in the geotechnical engineering that the internal pressure leads to the fracture of joints. The problem is simplified as one of a joint under I mode internal pressure in the finite rock mass，and solved by the near-joint-line method based on the failure criterion of rock bridge material and equilibrium equations. The relationship between the internal pressure and cracked region length along the joint line is obtained.
