扰动分析方法是用来分析两个含水层中控制水流的方程,这两个含水层被一个半渗透岩层分隔开来。上部含水层是潜水(非承压)含水层,下部是半承压含水层。近水平流的逼近法导出一个双含水层的耦合方程,尤其对潜水含水层来说,该方程为非线性的。参数扰动法对线性化方程和分解方程是一种简便方法。这里就两个简单问题介绍扰动方程的解析解法。 The disturbance analysis method is used to analyze the equations governing the flow of water in two aquifers that are separated by a semi-permeable rock formation. The upper aquifer is a submerged (non-pressure-bearing) aquifer and the lower part is a semi-confined aquifer. The approximation of the near-horizontal flow leads to a coupling equation for a double aquifer, which is nonlinear especially for submarine aquifers. The parameter perturbation method is a convenient way to linearize and decompose the equation. Here we introduce the analytical solution of the perturbation equation for two simple problems.
