山区铁路岩溶及危岩落石地段综合选线——以郑万铁路小三峡隧道中垌河方案研究为例

Comprehensive Selection for Railway Routes at Sections with Karst and Dangerous Falling Rocks in Mountainous Regions——A Case Study of Donghe River Scheme in the Small Three Gorges Tunnel of Zhengzhou-Wanzhou High-speed Railway

西南山区地形地貌险峻,地质复杂,存在工程实施难度大、造价高、工程风险大、工程弃渣难等问题。选线应结合地形地貌、不良地质、工程条件、工程造价等进行综合比较,选出一条经济合理的铁路线路。

The Southwest China is quite geomorphologically complex, rendering constructions here challenging, costly, risky and hard for slag dumping. For a railway route selection, geographic and geomorphic conditions, unfavorable geologies, engineering conditions, project cost and so on should be compared comprehensively for an economic and reasonable railway route.
