| 摘 要： | 地下水流数值模拟计算软件Visual MODFLOW的墙体边界(wall)又被称为水平流障碍边界(Horizontal-Flow Barrier,HFB),可用于模拟地下含水层系统中薄层、垂向和低透水性、对地下水水平流具有阻碍作用的物体.在分布有众多压扭性隔水断层的淮北地区,应用墙体边界模拟断层,用Winston提出的方法对与网格线呈夹角关系的断层水力参数进行修正,选取23条对研究区地下水流具有控制作用的断层,对研究区进行地下水流数值模拟.计算结果表明,研究区地下水流受断层的影响显著,应用墙体边界对断层进行模拟的方法能够较好地反映出断层的这种影响作用.图7,表3,参11.

| Abstract: | The Horizontal-Flow Barrier(HFB) Package,or Wall Boundary as it is referred to in Visual MODFLOW designed for groundwater numerical simulation,was developed to simulate thin,vertical,low-permeability features that impede the horizontal flow of groundwater.The groundwater numerical simulation to study area was carried through,simulating the faults by use of Wall Boundary,adjusting the hydraulic characteristics of the faults,which are at an angle to grid,through the method brought forward by Winston,and selecting 23 faults controlling the groundwater flowing in Huaibei city,which there are a number of compresso-shear and water-resisting faults.The results indicate that the groundwater flow in study area is influenced evidently by these faults,the method of faults simulation applying Wall Boundary could reflect the impact of the faults to the groundwater flow better.7figs.,3tabs.,11refs. |
