依托南昌轨道交通1号线中～子区间含砂砾富水复合地层地铁联络通道工程，针对施工过程中揭示的富水砂砾地层，对联络通道施工进行风险分析，建立了三维数值分析模型，分别探讨了富水条件下联络通道地层预加固、降水井降水结合地层预加固两种处理措施下联络通道施工后地层反应，据此提出了含砂砾富水复合地层处理技术方案。方案实际应用效果良好，有效控制了联络通道施工风险，可供类似地层条件参考。

Relying on the engineering of metro connected aisle in complex strata with watery sandy stratum of Zhong~Zi section in Nanchang rail transit line 1 , the risk of construction was analyzed for the watery sandy stratum re-vealed during the construction process.A three-dimensional numerical analysis model was built.The strata reac-tions after the construction of connected aisle under watery conditions by two treatment measures, one is stratum pre-reinforcement, and the other is stratum pre-reinforcement combined with precipitation by precipitation wells, were discussed respectively, and the technical treatment schemes for complex strata with watery sandy stratum were proposed.The practical application effect of the scheme was good, and the risk in construction of connected aisle was controlled effectively.It can provide reference for similar strata conditions.
