摘　　要：迎宾路口站小里程端站前设有单渡线,采用矿山法施工。而烈士公园南站—迎宾路口站区间工程地质、水文地质条件复杂,地表建构筑物众多,施工难度大。文章对该工程的周边环境及控制性管线分布、工程地质条件和水文地质条件进行分析,在此基础上分析工程隧道的风险源和施工重难点,以此为工程采取合理可行的措施提供技术支持。A single crossover is set in front of the small mileage terminal of Yingbin Road Station,which is constructed by mine tunnelling method.However,the South Martyrs Park Station-Yingbin Road Station section is with complex engineering geological and hydrogeological conditions and numerous surface structures,which is difficult to carry out construction.This paper analyzes the surrounding environment,controlled pipeline distribution,geological conditions and hydrogeological conditions of the project.On this basis,the risk sources and construction difficulties of the project tunnel are analyzed to provide technical support for the project to take reasonable and feasible measures.
