摘　　要：路基塌陷是影响我国山区道路安全的主要灾害形式,对山区道路安全产生了极大影响。文章针对路基塌陷,介绍组合式桥梁的结构形式及相应优势特点,然后结合某城市山区路段路基塌陷应急修复项目,分析组合式桥梁在路基塌陷应急修复当中的具体应用,对其内力分析、螺栓稳定性分析、承载钢索稳定性分析等应用要点展开详细探讨,工程应用结果表明,组合式桥梁应急修复技术的应用对于提升路基工程应急修复水平有积极作用。Subgrade collapse is the main disaster form affecting the road safety in mountain areas of China, which has a great impact on the road safety in mountainous areas. Aiming at the subgrade collapse, this paper introduces the structural form and corresponding advantages of the composite bridge,and then analyzes the specific application of the composite bridge in the emergency repair of subgrade collapse in combination with the subgrade collapse emergency repair project on a mountainous road section in a city. The application points such as internal force analysis, bolt stability analysis and bearing cable stability analysis are discussed in detail.The engineering application results show that the application of composite bridge emergency repair technology has a positive effect on improving the emergency repair level of subgrade engineering.
