摘　　要：以房山线北延工程某区间风井基坑为例,对深基坑降水与回灌过程建立三维数值模型,分析探讨了地下水模拟的可行性及准确性,并研究了降水与回灌相结合的效果以及对地下水位和地表沉降的影响。Taking the foundation pit of a certain section of the North Extension Project of Fangshan Line as an example,a three-dimensional numerical model is established for the precipitation and recharge process of deep foundation pit.The feasibility and accuracy of the simulation are analyzed and the combination of precipitation and recharge is studied.The effect and impact on water level and surface subsidence.
