摘要：
The natural mechanic condition of the rock mass project is classified according to its position and engineering mechanical state. And the determination methods of mechanical parameters in rock mass is summarized. In addition, ranked numerical calculation method is brought out in details. The mechanics characteristics of unloading rock mass is analyzed. After comparing unloading rock mass mechanics with loading rock mass mechanics, their intrinsical distinctions are also pointed out. It is pointed out that we should adapt different mechanical theory and means owe to its mechanical state.
