大西客运专线韩信岭越岭方案综合研究

Comprehensive Study on the Route Option of Hanxin Ridge Crossing on Datong-Xi'an Railway Passenger Dedicated Line

韩信岭是大西客运专线太原至临汾之间高程最高的分水岭地带,也是控制全线(段)技术标准、方案走向、施工工期和工程造价的关键地段。通过综合研究区域地形、地质条件,坚持地质选线、重大工程优先选址、环保选线、资源选线和横断面选线等基本原则,避开煤矿采空区的影响,充分论证太岳山山前大断裂对水文地质的影响,从工程角度对越岭方案进行充分的论述,同时还从环保的角度出发,尽量减少对泉域保护区和自然保护区以及地下水环境的影响,合理选择穿越韩信岭自然保护区的线路方案,保证了铁路安全可靠,综合效益最佳。

Hanxin ridge is the highest watershed between Taiyuan and Linfen on Datong-Xi＇an railway passenger dedicated line,and the key section controlling overall line technical standards,route orientation,construction period and construction cost.By comprehensive study of regional topography and geological conditions,this paper strictly followed the basic principles of geological route design,priority location of major projects,environmental protection route investigation,cross section selection and etc.,detoured the worked-out area of coal mining,fully considered the impact of large fractures in front of the Taiyue mountain on hydrogeology and discussed the ridge crossing option in detail from the engineering perspective.At the same time,in order to alleviate the impact on spring conservation area,nature resources and groundwater environment,the designers tried to make proper route selection through the natural conservation zone of Hanxin ridge to guarantee the safety and reliability of the railway and to obtain the maximum comprehensive benefits.
