The slope stage excavation process is: ( i) excavating the first part of the slope rock and exerting rock bolting and concrete shotcrete layer ( ii) excavating the second part and exerting the second layer rock bolting and concrete shotcrete layer. The next construction process is the same as the upper step. In this article, the bolting is simulated with one-dimension axial bar, the joint is simulation by no thickness Goodman element, the effect of blasting is calculated using dynamic stress method, the slope stability safety factor derives from using elasto-plastic finite element method of lo...
