摘　　要：山区高速公路地形、地质复杂,沟谷陡峭,河流环绕,短路基填筑、台背回填压实困难,桥隧相接不可避免,处理好短路基填筑、台背回填压实和桥隧相接问题对于工程运营安全、行驶舒适度意义重大。结合甘肃省成武高速公路工程实践,进行了对短路基填筑、台背回填处理、桥隧连接部处理的研究,提出不同的处治措施,可供同类公路工程设计和施工借鉴。Due to its geographical complexity and difficult terrain, expressways in mountainous areas, which are always passing through steep valleys and surrounded by rivers, faced difficulties in compaction for intervals in short subgrade sections, abutment backfill and connecting sections between bridges and tunnels. Such problems, if being well handled, are significant to the safe operation and comfortable driving. In this paper, based on actual project experience in Chengxian to Wudu Expressway, researches are conducted in regarding to compaction for intervals in short subgrade sections, abutment backfill and treatment for connecting sections between bridges and tunnels, and alternative measures are proposed, which can bring good reference for both design and construction of similar expressways.
