【Abstract】 The regularly jointed rock mass is considered as linearly anisotropic material and the stresses and deformations around a tunnel are analyzed based on the theory of complete plane strain.The complex variable method to solve this problem is described.Solutions in matrix form for circular holes are given with a discussion about the types of plane strain.The influence of joints on the stress distribution around the hole is shown by a numerical example.更多还原
