摘　　要：引入能反映裂隙剪胀特性的非线性弹塑性本构模型 ,从而考虑了裂隙非线性法向变形和剪胀对裂隙隙宽的影响 ,更实际地反映了裂隙变形对岩体渗透性的影响。A nonlinear elastoplastic model including dilatancy of joint rock masses is proposed. The influence of joint deformation on permeability of rock masses is considered more realitiably. The FEM program is developed with four freedom complete coupling method. The examples show that the model is reasonable and credible for the coupling analysis of stress and fluid flow.
