摘要
为了分析仙桃市应急水源地的开采潜力和开发利用方案,选择地下水模拟软件GMS中的MODFLOW模块,对研究区模型进行合理的边界条件概化,通过模型的调试和识别,确定可靠的水文地质参数,计算得到研究区允许开采量为1.561×108m3/a。对开采潜力进行评价分析,确定开发利用方案:宜开采深度为90~100 m,管径适用250 mm,采用30 m3/h的泵量取水,且保证抽水时间在每天16 h,需新增布设34眼,井距>500 m。
In order to analyze the exploitation potential and development and utilization scheme in Xiantao City Emergency Water Source,the authors choose the MODFLOW module from the groundwater simulation software GMS,make a reasonable boundary condition generalization for study area model,and through the model debugging and recognition,determine the reliable hydrogeology parameters,and the allowable exploitation quantity are calculated to be1.561×108m3/a.The exploitation potential is evaluated and analyzed,and the development and utilization scheme is determined:the appropriate mining depth is90~100m,the pipe diameter is250mm,pumping water with30m3/h,and to ensure that pumping time in16hours a day.It need layout34new eyes with over500m well spacing.
