| 摘 要： | 厦门海底隧道是我国建设的第一条海底公路隧道,其穿越的F1、F2、F3、F4四条断层破碎带处,洞体围岩软弱、破碎,流变属性十分明显.对该类岩石进行了室内三轴压缩流变试验,研究了岩石在不同围压和不同应力水平作用下轴向应变随时间的变化规律.试验结果表明,幂律型蠕变模型可以用来较好的模拟该类岩石除第三阶段蠕变以外的蠕变行为.

| Abstract: | Xiamen Subsea Tunnel is the first subsea road tunnel in China. The tunnel passes through the faultages F1, F2, F3 and F4 where the rock mass is rotten and cracked. Rheologlcal properties of this type of rock are remarkable. A series of triaxial compression rheological experiments were carried out. Based on the experimental results, the variance law of axial strain of specimens with time under different confining pressures and different deviatoric stresses is investigated. By comparing the experimental results and the results predicted from the use of power law creep model, it is shown that the power law creep model can be used to simulate the primary creep and the secondary creep of the rock. |
