Cause Analysis and Treatment Methods for Sudden Collapse of Tunnel Roof during Tunnel Excavation Process
During tunnel excavation and support,landslides are often caused by various reasons.In addition to strengthening prediction and prevention in advance,more attention should be paid to how to effectively organize landslide treatment after collapse.Accelerating the processing progress while ensuring safety and quality can minimize project losses and capital investment.This paper analyzes the causes of collapse during the excavation process of the ventilation pipeline tunnel in Shigu Water Source Project of Dianzhong Water Diversion,and describes the treatment methods,providing technical support for the subsequent collapse treatment of similar tunnels.
