摘　　要：公路坝式路堤是一种集水坝和路堤功能于一体的公路建筑物,其对于干旱、半干旱地区建设生态公路、改善生态环境、实现可持续发展具有重要意义。通过对甘肃省交通系统已建坝式路堤设计、施工及使用情况的调查,归纳分析了存在的问题及其产生的原因,讨论提出了公路黄土坝式路堤的选址、蓄水量、泄洪涵洞的设置及工法、边沟水的排向、防渗层设置、边坡设计、沉降(陷)处治及结合部处理等方法和措施。The dam-embankment is a highway structure having the function of both dam and embankment. It has vital significance to build ecological highway, to improve ecological environment and to achieve sustained development in dry and semi-dry areas. In this paper an investigation is given about the design, the construction and the use of dam-embankment highway structures which are finished and put to use in the highway system of Gansu Province. An analysis is made about the problems and their causes. The method and strategy of location selecting, water storage and flood discharge culvert in loess regions are put forward. And proposals about drainage direction of side ditches, seepage proof layer setup, side slope designing, settlement handling, joining part handling and so on are also presented.
