结合三峡永久船闸高边坡工程，在试验室条件下，对三峡岩体结构面的剪切刚度和法向刚度特性进行了专门试验研究。试验成果分析表明：剪切刚度量值决定于结构面本身的起伏糙度和强度以及法向应力的大小，法向刚度量值主要取决于结构面的张开状态及岩体的风化程度。
Combined with the high slope project of the permanent ship lock of the Three Gorges Project, special experimental studies have been carried out on the shear stiffness and normal stiffness of the structural plane of the Three Gorges rock under laboratory conditions. The test results show that the magnitude of shear stiffness depends on the roughness and strength of the structural plane itself and the magnitude of normal stress. The magnitude of normal stiffness mainly depends on the open state of the structural plane and the weathering degree of the rock mass.
