摘　　要：基坑降水容易引起周边地面沉降,为了保护基坑周边的建筑物常采用回灌技术。回灌的关键就是要保证受保护建筑物附近地下水位不产生过大变化,常规的理论计算受到边界条件等的限制,通过数值方法来模拟回灌后地下水位的变化,为工程建设中的回灌技术提供理论参考。Dewatering of foundation pit leads to ground settlement in the vicinity of the pit, therefore recharging is usually used to protect the surrounding buildings. It is important that the groundwater level in the neighborhood of the protected buildings varies less by means of recharging. Because the conventional theoretical calculations are limited by the boundary conditions concerned, the numerical method is adopted to simulate the groundwater level after the recharging, so as to provide a theoretical reference for the recharging technology in construction.
