自从我国大规模的第一个五年经济建设计划开始以后,由于许多新建城市,新建企业的供水需要利用地下水来解决,于是地下水的勘测工作就逐渐成为这些城市和企业,尤其是地表水缺乏地区的城市和企业在建设初期的重要工作之一。抽水试验是确定含水层渗透系数,影响半径和地下水流量的主要方法之一,因而抽水试验工作的好坏不只直接影响到对地下水流量的估算,同时也影响到给水工程的规划和设计,而这 Since the beginning of the large-scale first five-year economic construction plan in our country, due to the need to use groundwater for the water supply of new enterprises in many newly-built cities, groundwater surveys gradually become the cities and enterprises, especially the areas lacking surface water One of the important jobs for cities and businesses in the early days of construction. Pumping test is one of the main methods to determine the permeability coefficient of aquifer, the radius of influence and groundwater flow, so the pumping test work is not only directly affect the estimation of groundwater flow, but also affect the planning and design of water supply project, which
