The simulation of stage excavation of the stratified rock slope of Chang-Zhang expressway is carried out by using our own two-dimensional elastoplastic finite element program, in consideration of the influence of blasting and rock joint. The rock-mass's deformation, stresses and yielding state in the excavation process are analyzed respectively. The integral safety of the high slope for every stage excavation is discussed by using the method of lowing material's strength safety factor. The re...
