摘要
结合工程实例,分析了不良地质条件下软弱围岩隧道施工中发生坍塌的原因,并对洞内塌方段、塌方部位的前后影响段以及洞顶外部的塌方体处理施工技术措施做了详细介绍。经过综合治理,顺利地通过了塌方地段,可为类似隧道施工提供借鉴和参考。
Taking actual project as example,the paper analyzes the cause of tunnel collapse in weak surrounding rocks under poor geological conditions and gives detail description on engineering treatment for tunnel collapse sections,its influencing zones and landslide outside tunnel top. By taking comprehensive measures,construction successfully goes on through collapse sections,providing references for similar tunnel project.
