深基坑工程承压水降水存在诸多施工风险。通过分析,确定深基坑承压水施工的风险,水文地质调查确定承压水层的特性,围护、降水设计及优化确定合理的降水方案,围护施工和降水的过程以“四维”控制减少承压水降水的风险。从风险分析、调查、设计、施工全过程控制施工风险。
There are many construction risks for water pressure under pressure in deep foundation pit project. Through the analysis, the risk of deep foundation pit confined water construction is determined, the hydrogeological investigation determines the characteristics of confined aquifer, the design of envelope and precipitation, and the optimization of the optimal precipitation plan. The process of enclosure construction and precipitation is based on "Control reduces the risk of confined water precipitation. From the risk analysis, investigation, design, construction, the whole process of construction risk control.
