【摘要】：太行山隧道位于晋豫两省交界,为山西中南部铁路通道第二长隧道,地层岩性、新构造运动、地貌演化塑造了其独特的水文地质背景,Ω套谷、宽张裂隙发育,补给面积大,在Ω沟沟口、地形急剧变化带、构造轴部地下水易富存,隧道施工地下水顺宽张裂隙高压涌出。山西中南部铁路通道为国家重点工程建设项目,富水段落注浆堵水为主要的工程措施,本文在分析场地水文地质特征后,重点对帷幕注浆、周边注浆等方法的效果进行了分析。
[Abstract]:Taihang Mountain Tunnel is located at the junction of Shanxi and Henan provinces. It is the second longest tunnel of railway passage in central and southern Shanxi Province. Its unique hydrogeological background is shaped by stratigraphic lithology, neotectonic movement and geomorphologic evolution. At the entrance of 惟 gully, the topography changes rapidly, the underground water in the structural axis is easy to exist, and the groundwater is gushing out under high pressure along the wide tension fissure in tunnel construction. The railway passage in the central and southern part of Shanxi Province is a national key project, and the main engineering measures are grouting and plugging in the section with rich water. After analyzing the hydrogeological characteristics of the site, the effect of curtain grouting and surrounding grouting is analyzed in this paper.
