摘　　要：喀斯特地区地形条件特殊,公路选线较为困难。针对该问题,文章分析了喀斯特地区岩溶地貌的个体形态和组合形态,提出了喀斯特地区高速公路地形选线一般原则。将喀斯特地区选线问题进一步细化为孤峰(峰林)平原区路线选线问题、岩溶山区沿河线和越岭线路线布设问题,研究三种地形下的选线与布线方法,为喀斯特地区高速公路选线方法提供参考。The terrain condition is special in karst area, thus the highway route selection is difficult.In view of this problem,this article analyzed the individual form and combination form of karst topogra- phy,and proposed the general principle of expressway terrain route selection in karst area.The route selection problem in karst area was further subdivided into the route selection problem in single peak （peak forast） plain area,the layout of route along the river and the line across the ridge in karst moun- tain area, and studied the route selection and routing method under three kinds of terrain,thereby pro- viding the reference for expressway route selection method in karst area.
