ANEW ANALYTICAL MODEL AND ITS APPLICATION-OF JOINTED ROCK MASS
一个新的节理岩体力学分析模型及其应用

In general it is obiged to use expcrienced method in the design of undergrounb cavcrns or tunnels ow-ing to hte uncertainty in the deformation prediction of the rock mass.In this paper a new constitutiveequation expressing the mechannical properties of jointed rock mass is presented based on the assumptionthat the jointed rock mass or the jointed rock mass atter reinforcement with rock bolting can be consideredapproximately an eguivalcnt continuous medium. Considering thet their mechanical model fully expressesthe effect of the mechanical properties of rock mass and the interaction of joint surface with rock boltingand it can be treated with conventional solid mechanics by using FEM,this methed is expected to be usedwidely in the engineering practic.
