摘　　要：文章以北京地铁暗挖施工坍塌处理问题为研究对象,介绍了北京地区工程地质、水文地质、地铁施工的概况,并对引起坍塌的水文地质、施工行为、地下管线、振动荷载等诱因的作用机理进行了分析,进一步深化了对暗挖施工坍塌形成机理的认识;从坍塌预防和坍塌处理两方面归纳了坍塌的应对措施,以期为北京乃至类似地区地铁暗挖施工的坍塌处理提供参考。Using the handling of a collapse in a shallow-buried tunnel of the Beijing metro as an example, the topics of engineering geology, hydrogeology, and metro construction in Beijing are presented. The action mechanisms of the collapse incentives, such ashydrogeology, construction behavior, underground pipelines, and vibrating load are analyzed, deepening the understanding of the collapse-forming mechanism in shallow-buried tunnels. The countermeasures are summarized from the two aspects of collapse prevention and collapse treatment, providing a reference for similar projects.
