摘　　要：以广州番禺大道东侧地铁工程中矿山法暗挖下穿既有地铁隧道工程为研究对象,针对施工过程中的多重风险因素,开展安全风险评估与控制研究。介绍了矿山法暗挖下穿既有地铁隧道的风险,包括高空作业与物体打击风险、暗挖隧道坍塌风险等。采用层次分析法对各风险源进行定量评估,据此提出安全培训、监控系统、支护加固、电气防护规范等针对性控制措施。Taking the underground tunnel in the east side of Panyu Avenue in Guangzhou under through the existing subway tunnel project by mining method as the research object,according to the multiple risk factors in the construction process,this paper carries out safety risk assessment and control research,introduces the risks of underground tunneling through existing subway tunnels,including the risk of high-altitude operation and object strike,and the risk of tunnel collapse,uses analytic hierarchy process to evaluate each risk source quantitatively,according to which the safety training,monitoring system,support reinforcement,electrical protection standards and other targeted control measures are proposed.
