摘　　要：井点回灌法在基坑降水中的应用仍属于探索阶段,目前尚无成熟的设计方法作为参考。本文根据群井理论推导出了一种简便、可行的回灌设计方法,该设计方法提出了一种新的回灌量和回灌井间距的计算公式,并就施工中易产生问题的环节提出了控制措施。该研究成果成功用于武汉市二郎庙污水处理厂二期工程中,从该工程的实践中得到一些结论可用于类似工程作为实践参考。The application of well recharging in the dewatering of foundation pit is in primary stage,and at present no reliable design method could be consulted.A design formula is deduced based on the well group theory,which is simple and practicable.The new formulas for the calculation of the recharging rate and the distance of recharging wells are put forward,and the control measures for the possible engineering accidents in construction are presented.The research results have been successfully applied in the project of the sewage treatment plant in Erlangmiao of Wuhan,and some conclusions from the project could be consulted for similar engineering practice.
