| Abstract: | 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. |
