中文摘要：

选取巴顿提出的10条标准剖面线中的第1，10条作为人工模拟结构面的表面形态，并用水泥砂浆浇注成试件，在岩石双轴流变仪上，进行不同法向应力水平下的室内剪切蠕变试验。根据试验结果，利用过渡蠕变法、等时曲线法、蠕变曲线第一拐点法确定结构面试件在剪切状态下的长期强度，分析对比由该3种方法得出的长期强度的差异性，并基于本次试验结果讨论3种方法确定结构面长期强度各自在理论上与试验上的合理之处，同时也探讨3种方法的不足。该研究成果对于岩体长期强度试验方法的理论及其应用都是一次有益的探索。

英文摘要：

According to the first and tenth discontinuity lines from Barton＇s ten standard lines, shear creep test under different normal stress levels on biaxial rheological testing machine was conducted using cement mortar pouring artificial joint surface. Based on the creep test results, the transition creep law, isochronous curve and the first inflection point method were adopted to determine the long-term strength of the first and tenth discontinuity lines. Then, the differences of the long-term strength determined by these methods were analyzed and compared; and the deficiencies and reasonableness of these three methods were analyzed theoretically and experimentally. This study is an improvement of the theory and application for long-term strength analysis of rock mass.
