隧洞开挖支护过程中常因各种原因造成塌方,除了事前加强预报预防外,更应注重塌方后如何有效地组织塌方处理.在保证安全与质量的前提下加快处理进度,使工期损失与资金投入降到最低.通过对滇中引水石鼓水源工程通风管道洞开挖过程中发生塌方原因的分析与处理方法阐述,为后续同类型隧洞塌方处理提供技术支撑.
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.
