【摘要】：太行山隧道位于晉豫兩省交界,為山西中南部鐵路通道第二長隧道,地層巖性、新構(gòu)造運動、地貌演化塑造了其獨特性的水文地質(zhì)背景,新構(gòu)造運動及表生改造的共同作用,Ω套谷、寬張裂隙發(fā)育,補給面積大,在Ω溝口、地形急劇變化帶、構(gòu)造軸部地下水易富存,隧道施工地下水順寬張裂隙高壓涌出。深埋原生寬張裂隙無疑控制著富水段的分布,高壓涌水威脅隧道的施工安全和運營安全,而深埋原生寬張裂隙分布規(guī)律具隨機性且寬窄不一,其成因機理對研究富水段分布具有重要的理論與現(xiàn)實意義。
[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.
