| Abstract: | Three dimensional finite element method is adopted to simulate the enforcement effect of closely-set small-diameter pilot steel pipes for the tunnel in the fragmentized zone at fault in order to understand the deformational properties of surrounding rock during excavation.Calculation results and field measured data show that the pre-support technique adopted is effective and has guaranteed the safety of the excavation. |
| Keywords: | fault fragmentized zone tunnel 3D numerical simulation |
