摘　　要：以邹城西毛堂水源地为例,进行了历时33天的大型群孔抽水试验,获得了系统的试验数据。综合考虑含水层结构和地下水补径排条件,地下水流模型概化为第一类越流模型。基于群井干扰和水头降深叠加原理,利用最小二乘法和抽水试验资料,求得含水层渗透系数和贮水系数。Taking the West Maotang water source of Zoucheng as an example,this paper carried out a 33-days large-scale group hole pumping test.Comprehensively considering the aquifer structure and groundwater replenishment and drainage conditions,the groundwater flow model was generalized into the first type of leap-flow model.Based on the model of first type leaky system in groundwater dynamics,the principle of superposition of head drop and its analytical solution of group well interference was adopted,and the hydraulic conductivity and water storage were calculated by using the least square method.
