摘　　要：很多山区公路由于线形控制点较多,不可避免地出现高填方路基,相应的高填土涵洞也越来越多。随着公路使用时间的增加,一些高填土涵洞结构出现裂缝,在后期运营过程中存在较大的安全隐患。所以,论文对山区公路高填土涵洞设计要点展开分析,同时研究了增大截面加固法、托梁拔柱加固法、箱梁内嵌加固法对山区公路高填土涵洞的加固效果。Due to the large number of linear control points of many mountain roads, high fill subgrade is inevitable, and the corresponding high fill culverts are also more and more. With the increase of highway service time, some high fill culvert structures have cracks, and there are great potential safety hazards in the later operation process. Therefore, the key points of high fill culvert design of mountain roads are analyzed,at the same time, the reinforcement effects of different reinforcement design schemes on high fill culverts in mountainous roads are studied, such as increasing section reinforcement method, joist column pulling reinforcement method and box girder embedded reinforcement method.
