摘要
本文采用粘性流体有限元方法,分析抚顺龙凤矿巷道底鼓问题.采用反分析方法,通过调节边界条件和围岩粘性系数,使计算值逼近现场实测结果和模型试验结果,由此得到的粘性系数为10^(15)~10^(16)泊.
In this paper, the finite element method for viscous fluid has been used to analyse the floor heave in deep roadway on Longfeng Mine. The back analysis approch is adopted by adjusting the boundary conditions and viscosity coefficient of wallrrok, we make the calculated values approach to the values measured in insitu experiment and the equivalent material scale-down test. The viscosity coefficient of mudstone thus obtained is 1015 -1016 poise.
