Numerical Modeling of Shaft Collapse and Its Reinforcement Engineering
According to the engineering geological condition of the collapsed shaft, 3D-modeling software is used to simulate the surrounding rock-mass mechanics situation. And the William-Warnke failure criterion with 3-5 parameters was adopted. Based on the rockmass stress situation and the plastic deformation area obtained from the simulation process, the grouting in granular body, concrete frame, anchor and grouting integrated reinforcing project was adopted to reinforce the collapsed shaft. The collapsed shaft was used again after reinforcing.
