【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性的水文地质背景,新构造运动及表生改造的共同作用,Ω套谷、宽张裂隙发育,补给面积大,在Ω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。深埋原生宽张裂隙无疑控制着富水段的分布,高压涌水威胁隧道的施工安全和运营安全,而深埋原生宽张裂隙分布规律具随机性且宽窄不一,其成因机理对研究富水段分布具有重要的理论与现实意义。
[Abstract]:Taihang Mountain Tunnel, located at the junction of Shanxi and Henan provinces, is the second longest tunnel of railway passage in central and southern Shanxi Province. The stratigraphic lithology, neotectonic movement and geomorphological evolution have shaped its unique hydrogeological background. The joint action of neotectonic movement and supergene transformation, 惟 sheath valley, wide tension fissure development, large recharge area, sharp change zone of topography at 惟 gully, underground water in the structural axis is easy to exist, and underground water in tunnel construction flows out of high pressure along wide tension fissure. The distribution of deep buried primary wide tension cracks undoubtedly controls the distribution of water-rich sections. High pressure water gushing threatens the safety of construction and operation of tunnels, while the distribution law of deep buried primary wide tension cracks is random and narrow. The mechanism of formation is of great theoretical and practical significance for the study of the distribution of rich water section.
