怀邵衡铁路复杂不良地质区域线路方案研究

由于怀邵衡铁路在怀化南客站至安江站段存在铀矿、岩溶、断层等多种复杂不良地质,线路方案比选影响因素复杂,方案选择困难,采用地质条件分析及工程经济技术比较等方法,详细论述铀矿辐射、岩溶及岩溶水、断裂构造、高地应力、页岩气、围岩分级、工程投资、工期等因素对该段方案选择的影响,通过综合分析各种地质及工程经济技术条件,最终确定西线方案为合理的线路方案。

Research on Route Selection in Complex Unfavorable Geology Areas of Huai-Shao-Heng Railway

Route scheme selection of Huai- Shao- Heng Railway between Huai Hua Nan station and An Jiang station is complicated and difficult because of the complex and unfavorable geological conditions such as uranium,karst and faults. The article uses the geological condition analysis and engineering economic and technical comparison to address the influence on route selection in terms of uranium radiation,karst and karst water,faults,low stress,shale gas,surrounding rock classification,project investment,progress and other factors. The reasonable route scheme is ultimately determined through comprehensive analysis of geological and engineering economic and technological conditions.
