贵州复杂山区高速公路地质选线

Highway geological route selection in complex mountain area of Guizhou Province

地质因素为路线方案比选过程中的难点和主控因素。在贵州省思南至剑河高速公路第二合同段勘测设计过程中坚持地质选线,对龙塘坪岩溶路段和燕子岩滑坡路段线位、木蓬特大桥桥位进行优化,合理确定设计方案,在保证公路安全的条件下,降低了工程造价以及减少了项目运营维护费用,为复杂山区高速公路地质选线提供一定的参考。

The geological problems are the main difficulties and control factors of route selection.In the geological survey and design of the second contract section of Sinan-Jianhe Highway in Guizhou Province,we insisted on determining the reasonably line route with geological consideration,Optimizing the Longtangping Karst section,the Yanziyan Landslide section and the Mupeng Bridge location,what makes sense in reducing the cost of project construction and maintenance.The experience also provides reference value for highway geological route selection in complex mountain area.
