介绍了三峡工程船闸区硬性结构面的蠕变试验结果 ,着重分析了结构面在恒定荷载作用下的蠕变性态。在试验研究的基础上 ,提出了结构面蠕变的剪切蠕变方程。研究表明 :结构面的剪切蠕变位移不仅是加载持续时间的函数 ,且与所施加的法向压应力和剪切应力的大小有关 ,其蠕变方程中的各系数均随应力与结构面蠕变剪切强度比值的增加而增大 The creep test results of the rigid structural plane of the Three Gorges Project Lock Zone are introduced, and the creep behavior of the structural plane under constant load is analyzed emphatically. Based on the experimental study, the creep creep equation of structural plane is proposed. The results show that the shear creep displacement of the structural plane is not only a function of the loading duration, but also depends on the normal compressive stress and shear stress applied. The coefficients of the creep equation depend on the stress and the structural plane Creep shear strength increases with increasing ratio
