摘要
Abstract
Xitieche No. 2 tunnel is located in Shandong Province with a total length of 7851 meters. The surrounding rock of the tunnel mainly belongs to the Cambrian System limestone without large-scale dissolution. During the construction of Xitieche No. 2 tunnel, water seepage appeared in some sections of the tunnel. In order to analyze the impact of the drainage on the surroundings, this article theoretically calculates the range of dewatering influence within the tunnel region by using the pumping theory of big caliber well, and then analyzes the recharge, water-flow and drainage conditions based on the hydro-geological conditions within the region. And finally this article conducts a comprehensive analysis of the influence of drainage during construction on the hydro-geological environment nearby based on monthly regional rainfall over the years. According to the radius of influence, it is predicted that the width of 136~208 m would be affected by tunnel drainage. The analysis of water flow shows that tunnel drainage brings little effect on the wells in Quanyu village, but some on Xibu village. The analysis of rainfall indicates that the rainfall in 2013 is 42. 8% less than that in 2012 . The above analysis concludes that the tunnel excavation and drainage brings little effect on the wells in Quanyu village but some on Xibu village. The main cause for groundwater decline is attributed by much less rainfall in the two villages.关键词
