摘要
明确隧洞(道)建设对周围水环境的影响可以及时对相应地表水体与水资源做出科学合理的保护措施与合理调配。滇中引水狮子山隧洞的建设涉及多处水环境敏感点,在对区域自然地质背景与水文地质条件做出充足的资料收集与野外调查后,采用了数值软件模拟隧洞排水条件下的渗流场变化程度,并以此作为依据对敏感点进行了评价分析,结果表明:地下水水位下降主要在罗贤观北侧岩溶山地区域,隧洞建设对梁王山岩溶大泉和小官村水库的影响较小。研究成果为隧洞建设期的环境保护提供了有效的指导方向,研究思路在相关工程的勘察工作中具有一定的借鉴价值。
Clarifying the impact of tunnel construction on the surrounding water environment can make scientific and reasonable protection measures and reasonable allocation of corresponding surface water and water resources in time.The construction of Shizishan tunnel of Dianzhong water diversion project involves many sensitive points of water environment.After sufficient data collection and field investigation of regional natural geological background and hydro-geological conditions,numerical software is used to simulate the change degree of seepage field under tunnel drainage conditions.Based on this,the sensitive points are evaluated and analyzed.The results show that the decrease of groundwater level is mainly in the karst mountainous area on the north side of Luoxianguan,and the tunnel construction has little influence on Liangwangshan karst spring and Xiaoguancun reservoir.The research results provide effective guidance for environmental protection during tunnel construction,and the research ideas have certain reference value in the investigation of related projects.
