Abstract： Combined with the actual construction of Ji"nan Metro Yanqianhu Station project ， the silty clay stratum and precipitation difficulties are analyzed
By using precipitation and recharge technique in the silty clay stratum， the water level balance of the foundation pit is improved ， and the foundation pit construction monitoring data is effectively controlled ， which provides strong data and technical support for the safety of foundation pit excavation ， and reduces the construction risk of buildings surrounding the foundation pit and other construction risks
This construction method has achieved good
