摘要
采用室内剪切蠕变试验 ,通过对两组不同爬坡角的结构面进行剪切蠕变试验 ,得出不同应力水平下的蠕变试验曲线 ,并给出相应的剪切蠕变方程。研究表明 ,结构面的剪切蠕变和加载持续时间与应力水平的大小有关。
The rheological properties of rock mass discontinuities are researched by laboratory creep test. By analyzing the obtained rheological curve, a function relation formula between the strain and time is established. Study shows that the strain is not only related to time but also to the stress loaded. Finally the long term strength is determined.
