摘要
高速公路重载路线上小桥涵出现单板受力有两个方面的主要原因,车辆轴载大、超载以及梁板的横向连接设计不足,使整体刚度不能满足横向传递荷载需要。实践证明,宣大高速公路上采用的单板受力处治措施是可行的,能取得良好的效果,值得推广使用。
There are two main causes for appearing of force impact on expressway small bridge veneer under heavy duty（for example, heavy axial load, overloading, and insufficient transverse joint）. They make the whole rigidity measures taken to cannot satisfy the demanding of transverse loading transferring. It has been proved that deal this problem in Xuanhua-Datong expressway are feasible with good efficiency and is worth being popularized.
