首先整理归纳了回灌常用的方式及适用条件,然后从回灌场地的水文地质条件、回灌水源水质、回灌方案的经济和社会效益等方面讨论了影响回灌方案选择的具体指标。针对济南轨道交通R1线车站基坑工程,采用模糊层次分析和专家调查法对各站点的回灌适宜性进行了分析,确定了最适宜选做回灌的车站站点。
In this paper,the feature and applicable conditions of different artificial groundwater recharge methods are summarized,and from the aspects of hydrologic geology conditions,water quality and economic and social effects,factors that affect the choice of artificial groundwater recharge are discussed.Based on the foundation excavation engineering of Ji'nan Rail Transit R1,the FAHP( fuzzy analytic hierarchy process) combined with fuzzy comprehensive evaluation is performed to analyze the artificial groundwater recharge suitability of these foundations,and the most appropriate foundation excavation for recharging is confirmed.
