| Abstract: | This paper analyzes profoundly the influence factor of safety thickness of top slab of rock bedding in karst and mined out region, and the defects in traditional semi quantative analysis method of safety thickness of top slab of rock bedding of karst. According to the characteristics of stability of subgrade in karst and mined out regions on Tan Shao Expressway, this paper presents analysis means of three dimensional nonlinear finite element and enumerates the methods of the optimization theory to determine safety thickness of top slab of rock bedding, which provides reliable basis for treatment scheme design of subgrade in karst and mined out regions on Tan Shao Expressway. |
