【摘要】 隧道地下水动态监测是隧址区地下水环境保护的基础工作,通过在隧址区构建地下水动态监测系统,获取隧址区地下水动态监测信息,分析包括水量、水质、水温等变化规律,判识隧道涌水来源,并利用隧道工程水环境负影响评价体系,评价隧道建设产生的水环境影响,进而在此基础上,构建了该隧道工程的水环境保护体系。天坪寨隧道为在建达万高速公路控制性工程之一,通过对天坪寨施工情况和水文地质条件的调查,在隧址区布设了3个井泉监测点、2个堰塘监测点、2个煤洞水监测点以及对隧道排水和各处隧道内涌水点进行监测,构建了天坪寨隧道地下水动态监测系统。通过该监测系统,大量获取了隧址区各监测点水量、水质等动态变化信息,为地下水动态监测信息的应用研究提供了数据支持。通过对各监测点的水量和水质动态变化规律分析,隧道建设造成了堰塘T2的水量减少,双河口煤矿的干涸,以及凤凰坝煤矿一段时期的水量递减；并利用模糊聚类分析法确定了隧道涌水来源,其隧道进口段涌水与堰塘T2和麻地沟煤矿有关,隧道出口段涌水与双河口煤矿和风凰坝煤矿有关。此外,通过地下水环境影响负效应评价体系的构建,得出了天坪寨隧道建设产生的地下水环境负效应为中等的结论,并分析总结了天坪寨隧道施工过程中造成的环境问题和采取的环境保护措施,进而建立了包括隧道工程水环境动态监测与影响评价体系和水环境保护与污染防治体系两部分的隧道工程水环境保护体系。
【Abstract】 Tunnel groundwater dynamic monitoring is the fundamental work for groundwater environment protection in the tunnel area,this thesis proposes a monitoring system for dynamic of groundwater to get the dynamic monitoring information,analyze the variation of yield, quality, and temperature of the water, identify the sources of water inflow into the tunnel, evaluate the impact of the construction of the tunnel on water environment by using water negative effects evaluation in tunnel engineering, and built the system for water environment protection of the tunnel on the basis of that.The Tianping village tunnel is one of the control projects of Wan-Da expressway. Tianping village tunnel groundwater dynamic monitoring system is structured by establishing three wellspring monitoring points, two ponds monitoring points,two coal hole watermonitoring points, tunnel drainage points and the points of tunnel water gushing. A lot of dynamic information which provides data support for application research of groundwater dynamic monitoring information including the flow of water, the quality of water et.al of monitoring point water is gotten by the monitoring system. According to the analyzing of water quantity and water quality dynamic change rule of the monitoring points, the tunnel construction cause the reduction in quantity of water of ponds T2, the dry up of Shuanghekou coal mine and the diminishing water of Fenghuangba coal mine in a period of time. Fuzzy cluster analysis method is used to determine the source of water gushing of tunnel. The water gushing of Tunnel entrance relates to pond T2and madigoucoal mine. The water gushing of Tunnel export relates to Shaunghekou coal mine and Fenghuangba coal mine。In addition, through constructing the evaluation system of the groundwater environmental negative impact, obtains the conclusion that the negative effect of the Tian Ping Village Tunnel construction on groundwater environment is middle. Through the analysis of the environmental problems caused by the process of tunnel construction and environmental protection measures, establishs the environmental protection system of tunnel project on groundwater. This system contains water environmental dynamic monitoring and evaluation system on tunnel project, and contains water environmental protection and pollution prevention and control system.
