Study of Stability Assessment Method for Deep Surrounding Rock

Abstract:

According to the three characteristics of deep surrounding rock: high stress, high temperature and high seepage, the three field coupling control equation of temperature-stress-seepage are established, the finite element method is used for solution. Considering stress transference of surrounding rock after creep and deformation, the finite element incremental equations is deduced. Combining the finite element method and strength reduction method, The defect of deep surrounding rock stability that never quantitatively assess before was overcome. The proposed calculation method is applied to project, the analysis results show that the proposed method is feasible.
