【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。更多还原

【Abstract】 Taihangshan tunnel is located at the boundary between Shanxi and H enan province and is the second longest tunnel of Shanxi-H enan-Shangdong railway thoroughfare. Formation lithology,neotectonic movement and geomorphologic evolution shaped its unique hydrology geology background,which is the development of Ω-like valley and wide-tension f issure,large recharge area,groundwater enrichment at the mouth of Ω-like valley,the rapid changing topography and the tectonic axis section,groundwater wide-tension f issure emission with high pressure in tunnel construction. Shanxi-H enan-Shangdong railway thoroughfare is the national key construction project,grouting and ponding in water-rich section is the main engineering measures. This paper analyzed the hydrology geology features and emphasized the effect of such methods as curtain grouting and peripheral grouting.更多还原
