基于桥头两侧过渡段路基路面设计及施工技术应用过程中存在的问题,文章分析了过渡段路基路面结构作用的常见病害,并提出了优化设计以及施工技术应用的方式方法,其目的是为相关建设者提供一些理论依据。结果表明,桥头两侧过渡段路基路面跳车问题的控制,要从地基处理施工技术、后台填筑施工技术、搭板设置设计以及无搭板设置设计来实现结构优化。 Based on the problems existing in the design and construction of subgrade and pavement on the transitional sections of bridge head, the article analyzes the common defects of the subgrade and pavement structure in transitional section and puts forward the ways and means of optimizing design and application of construction technology. Builders provide some theoretical basis. The results show that the optimization of the structure control is from the foundation treatment construction technology, the backfill construction technology, the design of the slab setting and the design of the slab-free setting in the transitional section of the bridge head.
