摘要/Abstract

摘要： 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。

Abstract: The creep test results on hard structural plane in T GP's permanent lock regions are represented,and the creep status of structural plane under the acting of a constant load are emphatically analysed.Based on exp erimental study,the shear creep constitution equations of structural planes are proposed.The study results indicate that the shear creep displacements of struct ural planes are not only a function of duration of added load,but also depend on the magnitudes of exerted normal compression stresses and shear stresses.All co efficients in these creep equations increase with increasing of the ratio of she ar stress and creep shear strength of structural planes. 
