| 摘 要： | 在详细分析了龙子湖地区水文地质条件和工程地质条件的基础上,根据龙子湖的设计方案,指出龙子湖建成后可能存在渗漏量过大的问题,从而影响该区的生态环境等环境地质问题。本文建立了三维渗流数值模型,通过数值模拟证实了龙子湖建成后确实存在渗漏量过大的问题,并为解决这些环境地质问题提供参考方案,还预测分析了环境水文地质条件改变后可能进一步出现的问题并提出了相应的解决方案。

| Abstract: | In this paper the hydrogeological and engineering geological condition are analyzed in detail.According to the design plan of Longzi Lake,the problem of large seepage volume might occur after the completion of the lake project.The groundwater level might rise because of the seepage of Longzi Lake and it might influence the entironment surrounding the lake.A three dimensional model of seepage simulation was established and the results of the computation proved the problem of large seepage volume to be true.Alternative plans are put forward which may help to solve the problem.Other new problems due to the change of the hydrogeological and engineering geological conditions are forecasted and analyzed.Finally,the methods to solve the problem are advised. |
