By analyzing the causes of deep collapse and roof collapse in the super long span renovation and expansion tunnel,a series of solutions have been proposed,including strengthening geological exploration,optimizing construction methods,and strengthening support measures.In order to verify the feasibility and effectiveness of these processing technology solutions,conducted simulation experiments and engineering practices.The results show that these treatment techniques can effectively control the occurrence of deep collapse and roof caving in tunnels,and improve the safety and reliability of the project.
