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。 Based on the viscoelastic theory of Kelvin model, the problem of bottom drum in deep rock roadway was studied, and the rheological analysis was carried out. The time-displacement analytical solutions of bottom rock drum phenomenon in deep rock roadway were given, Some Rules of Time Evolution. Under the condition of roadway unsupported, the displacement curve of about 150 h after excavation of the roadway gradually converges. The research results have certain guiding significance and reference value for the governance of the bottom drum phenomenon in deep rock roadway.
