客运专线高标准铁路,穿越复杂山区的工程地质选线是非常困难而且至关重要。要在满足平纵面高标准条件下,综合考虑隧道、路基、桥梁等工程设置,更重要的是最大限度地避免天然地质灾害和工程诱发地质灾害。介绍合武铁路大别山地区的工程地质综合选线,经过前期地质选线推荐的墩义堂至麻城北站段3个线路方案的比较情况,对所述方案的工程地质条件进行分析比较,选择合理山区线位,从中推荐工程地质条件较好的方案Ⅲ。经过施工运营,验证了所选方案施工顺利、运营良好,方案选择合理。
Passenger Line High-standard railway, crossing the complex mountain engineering geological alignment is very difficult and crucial. To meet the high standards of flat surface conditions, considering the tunnels, subgrade, bridges and other engineering settings, more importantly, to maximize the avoidance of natural geological disasters and engineering-induced geological disasters. This paper introduces the engineering geological comprehensive route selection in the Dabie Mountain area of the Kwu-Wu Railway. After comparing the three schemes recommended by the pre-geological route selection of the Mudanjiang-Macheng North Station section, the engineering geological conditions of the project are analyzed and compared, Mountain line, which recommended a better geological conditions of the program Ⅲ. After construction and operation, the selected project has been successfully constructed and operated well with reasonable options.
