路桥过渡段的路基路面结构设计方法

Design Method of Subgrade and Pavement Structures in the Transition Region Between Road and Bridge

归纳了路桥过渡段不平顺和跳车问题的基本力学原理,并阐述了其影响.提出可以从道路路基和路面2个层面进行设计把控,提高过渡段的设计质量,从而降低病害发生概率.例如,对不良地质进行处理、提高路基填料质量和压实度、增强路基边坡稳定性、设置路面桥头搭板等措施.

The basic mechanics principle ofroed and bridge transition section irregularity and jumping problem is summarized, and its influences are analyzed. It is suggested that design methods ofsubgrade andpavement could be utilized to improve the design quality of the transition section so as to reduce the probability of disease occurrence, which includes reinforcement of unfavorable geology, quality control and compaction improvement of the subgrade filling, stability strengthening of subgrade slope, and setting pavement approaching slab etc.
