中文摘要：

建筑工程降水往往伴生水资源浪费和地面变形等环境问题,人工回灌是解决这些问题的有效手段之一。影响工程降水中人工回灌的条件有回灌场地水文地质条件、回灌水源水质和水量及回灌方案的经济可行性等因素。就工程降水中出现的问题,提出资源补充型回灌和应力稳定型回灌方法,并给出了适用条件;根据工程降水水质特点及现有的地下水人工回灌相关水质标准,提出工程降水回灌水质的控制指标主要为悬浮物、浊度、一般污染性指标、微生物指标及重金属等。针对目前人工回灌在工程中存在的可回灌性低的问题,进行了影响入渗速率因素研究,为今后开展促渗关键技术提供理论支持。

英文摘要：

The waste of water resources,ground deformation and other environmental issues are often associated with construction industry dewatering.Artificial recharge is an effective mean to solve these problems.Influential factors of artificial recharge in engineering dewatering are hydrogeological conditions of recharge site,water quality and quantity of recharge and the economic feasibility of recharge program.For the problems in the engineering dewatering,the authors propose two kinds of recharge methods including water resources supplement recharge and stress stable recharge,and propose the applicable conditions.According to the features of construction dewatering and the artificial recharge standards of native grounduater,it was suggested that the water quality control indicators of engineering dewatering are suspended solids,turbidity,general pollution indexes,microbial indexes and heavy metals.Aiming at the problem of low recharge in artificial recharge of construction,the factors that affect the infiltration rate is studied to give theoretical support of the key technology of promotion infiltration in future.
