摘要
基于Boussinesq方程,采用ADM法建立地下水解析模型,分析ADM法的模拟精度,并改进该方法边界条件表述方式,以减少ADM法计算误差。将改进ADM法应用于沧县地区,通过对比模拟值与实测值,改进ADM法能较好地模拟研究区的地下水位分布及变化、降落漏斗分布情况等,计算过程方便快捷。利用地下水解析模型率定的参数对研究区进行地下水数值计算,将两者结果进行对比分析,基于改进ADM法的地下水解析模型方法简单,计算效率高,总体来说模拟效果理想。
Based on the Boussinesq equation,an analytical model of groundwater was established using the ADM method.The simulation accuracy of the ADM method was analyzed,and the boundary condition representation of the method was improved to reduce the calculation error of the ADM method.The improved ADM method was applied to the Cang County area.By comparing the simulated and measured values,the improved ADM method can be used to simulate the distribution of groundwater level in the study area.The calculation process is convenient and quick.The groundwater numerical calculation of the study area was conducted using the parameters determined by the groundwater analytical model,and the results were also compared.The groundwater analytical model based on the improved ADM method has a simple method and high calculation efficiency.Overall,the simulation results are satisfactory.
