在柱坐标系下,利用贝塞耳函数和基函数提出了满足地下水流动边界条件的降深试探函数;采用伽辽金法原理,推导了层状非均质各向异性越流承压含水层中地下水非稳定流的有限层方程,建立了地下水流动的有限层分析方法。在此基础上,编制了相应的计算程序实现了有限层方程的求解。经典算例的解析解与有限层解的对比分析验证了本文方法的正确性和有效性。
Under the cylindrical coordinate system, the deepening trial function satisfying the groundwater flow boundary conditions is proposed by using Bessel function and basis function. The principle of Galerkin method is used to derive the stratified heterogeneous anisotropic overpressure aquifer In the finite layer equation of groundwater unsteady flow, a finite layer analysis method of groundwater flow is established. On this basis, the corresponding calculation program is compiled to solve the finite layer equation. The comparative analysis between the analytical solution and the finite layer solution of the classical example proves the correctness and validity of the method in this paper.
