【摘要】 三峡地下电站厂房窑洞口围岩属于一种断续节理裂隙切割的节理岩体，对主厂房与窑洞口相接处围岩的稳定情况，应用三维加锚节理裂隙岩体的本构关系、损伤演化方程来评价此类岩体稳定性和变形行为。结果表明所建模型是有效的。更多还原

【Abstract】 The rock mass surrounding underground powerhouse is cut by well-developed discontinuous joints in right bank of the Three Gorges project. The stability of the surrounding rock mass in the exit of powerhouse is concerned by the designer. A 3D constitutive laws and the damage evolutions of bolted discontinuous jointed rock mass are used to evaluate the stability and deformability of the surrounding rock mass during excavation and supporting. The calculated results indicate that the present laws and evolutions are available.更多还原
