摘要
利用凯尔文模型的黏弹性理论研究了深部岩石巷道出现的底鼓问题,进行了流变分析,给出了深部岩石巷道底鼓现象的时间—位移解析解,提示了深部岩石巷道底鼓现象时间演化过程的一些规律。在巷道不支护状态下,研究巷道开挖后约150 h位移曲线才逐渐趋于收敛。研究成果对深部岩石巷道底鼓现象的治理具有一定的指导意义和参考价值。
By means of the viscoelastic theory of Kelvin model, the paper studies the problem of floor heave in deep rock roadways, carries out rheological analysis, gives the time-displacement analytic solution, and prompts some laws of the process of time evolution of floor heave phenomenon in deep rock roadways. In the state of not supporting roadways, the displacement curve gradually converges in about 150 h after roadway excavation. The results have some significance and reference value for controlling phenomena of floor heave in deep rock roadways.
