The Application Study Of Tianping Village Tunnel Ground Water Dynamic Monitoring Information

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.
