复杂地质条件下隧道塌方涌水处理技术措施

Technical measures for treatment of tunnel collapse and water gushing under complex geological conditions

在隧道掘进过程中造成塌方的因素很复杂,地质因素、施工因素、管理因素等均可能造成隧道塌方。正确分析塌方的原因,有针对性的处理措施是解决隧道塌方的有效处理方法。结合隧道塌方工程实例,采用注浆加固、锁脚锚杆加固拱架、喷混凝土补强、排水孔施工等综合处理方案处理复杂塌方,同时为类似工程事故的处理提供借鉴。

In the process of tunnel tunneling,geological factors,construction factors and management factors may cause tunnel collapse.Correct analysis of the primary cause of the collapse and targeted treatment measures are effective methods to solve the tunnel collapse.Combined with the example of tunnel collapse engineering,this paper adopts grouting reinforcement,anchor anchor anchor reinforcement arch,shotcrete reinforcement,drainage hole construction and other comprehensive treatment schemes to deal with complex collapse,and provides reference for the treatment of similar engineering accidents.
