摘要
某连续刚构桥在施工过程中出现了底板崩裂情况,介绍该桥底板崩裂的原因以及修补加固的方法,并进行了底板修补的有限元仿真分析,通过结构分析及动静载试验表明加固效果良好。
The bursting cracks occurred in the bottom slab of a continuous rigid-flame bridge during construction. In this paper, the causes leading to the bursting cracks, method for repairing and strengthening the cracks are presented, and the finite element simulation analysis of the repairing was carried out. The structural analysis, static and dynamic tests made for the slab prove that the effect of the repairing and strengthening is good.
