应用地下水径向非稳定流理论求解水文地质参数的方法较多,笔者提出的适用于常见u值范围(0.001—1)的新直线法,其适用时段较雅各布直线法推前20倍,从而可充分利用抽水初期和远观测孔资料,为缩短抽水时间、降低试验成本提供了可能性。笔者将新直线法用于胶济铁路复线高密、兰村西两给水站潜水完整井的水文地质试验中,初见成效。两给水站水源井分别建于姚哥庄站西胶河东岸、李哥庄站西大沽河东岸的高河漫滩
There are many methods to solve hydrogeological parameters by applying the theory of radial unsteady flow of groundwater. The new straight line method proposed by the author for the common u value range (0.001-1) is 20 times more applicable than Jacobs straight line method, Which can make full use of the early and far-flung pumping data, which can shorten the pumping time and reduce the cost of testing. The author will use the new straight line method for high-density Jiaoji Railway double-track, Lancun West two water stations to complete the well hydrogeology test diving, initial success. Two water supply station water wells were built in Yao Gezhuang station east of the West plastic River, Li Ge Zhuang Station West Dagu River floodplain
