摘要
西(安)十(堰)高铁山阳—郧西段位于秦岭南麓,地形高差大、河谷深切,地质条件复杂,开展山阳—郧西段岩溶隧道比选方案水文地质条件研究,对线路方案的选择具有现实意义。从地形地貌、地质构造强烈程度、岩溶发育强度、隧道穿越含水岩组长度及其富水透水性、隧道与岩溶水系统的密切程度、岩溶水主要赋存状态、隧道所处地下水径流带、可能产生的突涌水点、隧道正常和最大涌水量、隧道可能造成的环境水文地质问题的严重程度等10个方面对隧址区岩溶隧道比选方案水文地质条件进行了研究,研究表明,IDK线取直方案岩溶隧道水文地质条件略优于DK线绕行方案秦楚隧道。
The Shanyang-Yunxi section of the Xi'an-Shiyan high-speed railway is located at the southern foot of Qinling Mountains,with large topographic differences,deep valleys and complex geological conditions.It is of practical significance to study the hydrogeological conditions of the alternative schemes for karst tunnels in the Shanyang-Yunxi section.Based on the landform,geological structure intensity,karst development intensity,rock tunnel crossing the water cut length and its rich water permeability,the close degree of tunnel and karst water system,main occurrence state,tunnel karst water of groundwater runoff belt,can produce sudden flood water points,normal and maximum tunnel water inflow,tunnel may cause the severity of the environmental hydrogeological problems,etc.The hydrogeological conditions of the comparison scheme of karst tunnel in tunnel site are studied from these 10 aspects.The study shows that the hydrogeological condition of IDK line straightening scheme is slightly better than that of DK line winding scheme in Qinchu tunnel.
