东山供水工程8#隧洞对泉之头村泉水影响分析

Analyzing the Influence of Excavating NO.8 Tunnel of the Dongshan Water Supply Project on Quanzhitou Spring

8#隧洞沿线主要涉及武乡县石盘镇泉之头、北南沟、玉品三个村庄。由于8#隧洞轴线距离沿线各村庄的泉水或井水较近,隧洞施工开挖过程中有可能对沿线村庄泉、井供水水源产生一定的影响。文中就8#隧洞施工开挖过程中对泉之头村泉水的影响进行分析评价,重点介绍了隧洞段及沿线各村庄泉水、井水的水文地质条件和它们之间的水力联系,在此基础上,为工程渗水处理设计和施工提供处理建议。

Along the NO.8 tunnel line of the Dongshan Water Supply Project,there are three relevant villages： Quanzhitou, Beinangou and Yupin Village of Shipan Town in Wuxiang County.Because the tunnel＇ s axis is close to the spring or water well of these villages along the tunnel, so the possibility may exist that the process of excavating the tunnel may make certain impact on the water supply of the spring or water wells.The paper analyzes and asseses the influence of excavating the tunnel on the Quanzhitou spring, emphatically introduces the hydrogeologic conditions of the tunnel section and the spring ＆ water wells of these villages along this tunnel, and narrates their hydraulic relationship. On the basis of this analysis, the paper puts forwad some suggestions for engineering water-weeping treatment design and construction.
