摘要: 为解决隧洞建设对周边地下水环境影响的问题,以滇中引水工程海东隧洞为研究对象,利用专门水文地质调查测绘、勘探、观测等技术手段,以及解析法、数值法等研究方法,对线路区岩溶水系统水文地质特征及与周边地下水环境的影响关系开展了系统研究,从地下水环境影响角度对海东隧洞选线方案进行了合理优化,推荐选择对地下水环境影响较小的B线方案。此案例剖析为引调水工程隧洞方案比选的分析评估思路提供参考。

Abstract: In order to alleviate the impact of Haidong tunnel construction in the water diversion project in central Yunnan Province on groundwater environment, we investigated into the hydrogeological characteristics of karst water system and the groundwater environment in the tunnel route area by comprehensive means inclusive of hydrogeological survey and mapping, prospecting and observation, as well as analytical and numerical approaches. We also optimized the route scheme of Haidong tunnel in consideration of its impact on groundwater environment, and recommend the line B scheme which has less impact on groundwater environment. The present research offers a reference for the selection and comparison of tunnel scheme for water diversion project.

Key words: water diversion project in central Yunnan Province, tunnel route selection, karst water system, hydrogeological characteristics, groundwater environment
