Abstract: The mathematical cover has relative independence to physical grid, so the generation of cover system for numerical manifold method is more flexible and convenient than finite element grid, but in some physical grid conditions, it has some dependence to physical grid as same as finite element method. Have discussed the effects of crack and boundary line in rock mass to the generation of cover system for numerical manifold method, point out that mathematical cover must suit with crack and boundary line in rock mass, and put forward corresponding method to form the cover system for numerical manifold method, it is helpful for application of the numerical manifold method in rock mass engineering.

Key words: numerical manifold method, cover system, rock mass, physical grid
