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 hydrogeoIogicaI and engineering geoIogicaI condition are anaIyzed in detaiI. According
to the design pIan of Longzi Lake,the probIem of Iarge seepage voIume might occur after pIetion of the Iake
project. The groundwater IeveI might rise because of the seepage of Longzi Lake and it might infIuence the entiron-
ment surrounding the Iake. A three dimensionaI modeI of seepage simuIation was estabIished and the resuIts of the
computation proved the probIem of Iarge seepage voIume to be true. AIternative pIans are put forward which may
heIp to soIve the probIem. Other new
