引言在大部分的排水和供水系统中,井群的几何形状是根据最大效率的抽水量来选择的。例如对于长沟(例如在含水层中安装水管所需者)的地下水位,通常就是在沟的二边设置成排的井或井点来降低的。同样,矩形井阵一般说来对于基坑排水最为有效。每排的井数和井距主要取决于要抽取的渗流水量和许可的抽水时间。与这类问题有关的工程师们,常常面临一 Introduction In most drainage and water supply systems, the geometry of the well group is selected based on the maximum efficiency of pumping. For example, the groundwater level of a long trench (e.g., required to install a water pipe in an aquifer) is generally reduced by providing a row of wells or well points on both sides of the trench. Similarly, rectangular well arrays are generally the most effective for draining foundation pits. The number of wells and well spacing in each row mainly depends on the amount of seepage water to be extracted and the permitted pumping time. Engineers related to this type of problem often face a
