摘要
为了减小基坑降水对周边环境及隧道的影响,以实际工程为例,从降水设计到现场实施全过程进行分析,结果表明在坑外设置回灌井并采取精细的水位控制可有效的控制因降水而引起的隧道沉降。
In order to reduce the impact of foundation pit precipitation on the surrounding environment and tunnel,this paper analyzes the whole process from precipitation design to on-site implementation using actual projects as an example,and the results show that setting recharge wells outside the pit and adopting fine water level control can effectively control tunnel settlement caused by precipitation.
