渗透反应墙( PRB)的设计是在水文地质数据充分的情况下建立水动力模型进行试验来确定的。由于水文条件随季节变化给PRB设计参数造成了误差。以某尾矿为例,在获得模拟区域整体水文地质数据之后,通过Visual Modflow建立了合理的数值模型。在验证模型合理的情况下,结合不同补给排泄条件下的模拟结果,合理预测了渗透反应墙安装位置、走向以及上部埋深。得出在尾矿库南部南偏东9°方向548 m以内安装渗透反应墙为适宜,且走向垂直于粒子追踪路径。渗透反应墙上部埋深范围取91.11m>h>87.60m。通过与传统方案参数在成本及修复作用作对比研究,得知基于Visual Modflow选取的渗透反应墙上部埋深及位置优于传统方案所取,两种方案的走向偏差较小,对地下水的修复及成本影响相差不大。所以基于Visual Modflow选取的PRB参数比传统方案参数更优,可为PRB设计的参数选择提供依据。

Under the condition of the hydrogeology information is sufficient,the hydrodynamic model experiment was es-tablished and tested to design permeable reactive barrier( PRB) .Due to the hydrological conditions change with the sea-sons caused PRB parameters have deviation.Taking a tailing as example,after the overall hydrogeology data of simulation district was obtained,the reasonable numerical model was established by Visual Modflow.After verifying the model is rea-sonable,combined with the simulation results in different supply and discharge,the location,strike,and the upper buried depth of permeable reactive barrier were predicted.The paper concluded that permeable reactive barrier was installed in the south of the tailings within 548m south by east 9°as appropriate.Permeable reactive barrier’s direction is perpendicu-lar to the particle tracking path.The upper buried depth of permeable reactive barrier range from 91.11 m>h>87.60 m.By compare with the cost and repair function in the traditional scheme parameters,the location,and the upper buried depth of permeable reactive barrier based on the Visual Modflow are superior to the traditional scheme.The strike of two plans only have small deviation,which has small impact on the cost repair effect.So parameters selected by Visual Modf-low than traditional scheme better,can provide the basis for parameters selection of PRB design.
