摘要
大山哨隧洞是黔中水利枢纽工程桂松干渠起点,隧洞全长8610m,为桂松干渠的控制性工程。由于工程地质条件为岩溶地质,所以必须加强对其水文地质条件的分析。以黔中水利枢纽工程桂松干渠大山哨隧洞为例,阐述了隧洞开挖抽排水对环境地质问题的影响,并对其进行补、排、径流关系分析。
Dashanshao tunnel is a starting point Guizhou Province,tunnel length 8610m and a engineering geological conditions, the analysis of Guisong canal for hydro-junction in the middle part of control project for Guisong canal. Because of the karst of the hydrogeological condition has to be strengthened. Taking Dashanshao tunnel as an example, the effect of the tunnel excavation drainage on the environmental geology is described , and its recharge, discharge, runoff relationship is analyzed.
