摘　　要：针对苏锡常地区微承压含水层厚度薄、颗粒细,采用传统的成井工艺施工一般出水量较小、易淤塞的现状,研究采用大口井、子母井与排井等不同井型开采微承水的工艺.以常州湖塘、吴江同里与湘城区黄埭3个示范工程为例,研究设计了大口井、排井与子母井平面结构、成井结构与施工工艺,并对各个开采工艺下的出水量与水质变化进行评价.根据示范工程的试验结果与微承压水的水文地质条件,进行了苏锡常地区微承压水取水工程的适宜性分区,该分区结果对微承压水取水工艺的设计具有指导意义.In allusion to the problem of little water yield and more easy blocking up using the traditional construction well technology for the thin thickness and fine particle micro-confined aquifer in Suzhou-Wuxi-Changzhou area,this paper studys the micro-confined groundwater mining engineering and technique by the large-diameter well,daughter-parent well and arrangement well.Taking the three demonstration projects of Wutang in Changzhou,Tongli in Wujiang and Huangdai in Xiangcheng district of Suzhou as examples,we study and design the planar structure,dig a well structure and construction technology of the large-diameter well,daughter-parent well and arrangement well,and evaluates the water-well yield and changes in water quality under the mining technology.According to test results and hydrogeological conditions of the micro-confined groundwater,we conduct the mining technlogy appropriate zoning for the micro-confined aquifer in Suzhou-Wuxi-Changzhou,the zoning results have guidance significance to the mirco-confined aquifer mining technlogy planning.
