摘要
通过蠕变模拟试验和数值方法的对比分析，研究了巷道底臌机理以及采取底板加固和底板切缝防治方法后，巷道围岩变形、破坏等随时间的变化，并探讨了防治参数对底臌的影响。
By means of the contrast analysis of creep simulation test and numerical meth od, the mechanism of roadway floor heave has been studied. The surrounding roadway deformation and the failure zone have been analyzed before and after taking prevention measures. Effects of prevntion parameters to floor heave have been discussed.
