山区高速铁路工程高路堤与高架桥的选择分析

以渝黔山区高速铁路工程为依托，结合铁路所经的地质条件对贵州省喀斯特核心区高路堤与高架桥比选，从地质、路线总体设计、节约土地、环境保护、文物保护、工程可靠度、沉降与轨道平顺性、全寿命周期成本方面进行了分析，研究结果表明:对于渝黔山区高速铁路工程的选线设计，高架桥较高路堤有明显的适应性。

Analysis on Selection of High Embankment and Viaduct Bridge in Express Railway Engineering in Mountain Area

Based on express railway engineering in Chongqing-Guizhou mountain area and combined with the geological conditions of the places the railway line passes through in the core region of karst Guizhou Province, to carry out the comparison against high embankment and viaduct bridge through the analysis on geology, overall line design, land saving, environmental protection, cultural relics preservation, engineering reliability, settlement, track regularity, and life cycle cost. The research results show that for the design on route selection for express railway engineering in Chongqing-Guizhou mountain area, viaduct bridge has significant adaptability compared to high embankment.
