... is discussed from three aspects: the initial material parameters, meshing and transformation of joint parameter. To verify its effectiveness in approx- imately simulating continuous medium, a numerical analysis of a roadway with high strength will be carried out. Finally, an excavation simulation of a roadway...

... and full-slip conditions, first and then a comparison between closed form solutions and numerical analysis are made. Numerical analyses are performed using finite element code (ABAQUS program). According to the numerical results, some practical suggestions for using closed form solutions for ovaling...
