摘　　要：地质条件可能引发的工程风险主要包括安全风险、质量风险、工期风险、环境风险和投资风险。岩土工程勘察文件应重点关注安全风险和质量风险。从电缆隧道的施工工法和工序出发,分析竖井支护开挖、竖井地下水控制、隧道主体施工过程中的地质条件可能带来的风险,根据工程地质条件进行地质风险识别。建议参考轨道交通风险控制经验分层级建立地质风险清单,制定风险控制措施。The engineering risks that may arise from geological conditions mainly include safety risks,quality risks,construction period risks,environmental risks,and investment risks.Geotechnical engineering survey documents should focus on safety and quality risks.The construction methods and procedures of cable tunnels were studied,and various risks during the excavation of shaft support,underground water control in the shaft,and construction of the main body of the tunnel were analyzed.Geological risk identification was carried out based on the engineering geological conditions.It is recommended to establish geological risk lists and develop risk control measures based on the experience of risk control in rail transit.
