摘　　要：岩溶地区地形地貌复杂,地下水资源丰富,常会导致突水涌泥等情况出现,极大地增加了施工难度。基于大量岩溶地区选线的经验,以贵州省首条PPP铁路项目瓮马线岩溶区傍行古暗河陆家寨隧道为工程依托,结合地质条件、工程条件、城镇规划、工程造价等因素,提出了短隧方案、中隧方案、长隧方案及沿河西大道桥梁方案,再对各个方案进行综合评价分析选出“短隧方案”为最优方案。The karst area has complex landform and rich groundwater resources,which often leads to water inrush and mud gushing,which greatly increases the construction difficulty.Based on the experience of route selection in a large number of karst areas,this paper proposes a short tunnel scheme,a medium tunnel scheme,a long tunnel scheme and a bridge scheme along the West Avenue of the River by taking the Lujiazhai Tunnel in the karst area of Wengma Line,the first PPP railway project in Guizhou Province,as the project support,in combination with geological conditions,engineering conditions,urban planning,project cost and other factors,and then selects the’’short tunnel scheme’’as the optimal scheme through comprehensive evaluation and analysis of each scheme.
