预制小箱梁桥拓宽施工工艺分析

On analysis of widening construction craft of precast small box girder

介绍了通车下交通组织及分时分段方案,以某预制小箱梁桥拓宽工程为例,通过有限元分析模型,分析计算了该桥梁的受力性能和拓宽横向分布系数,为预制小箱梁桥拓宽施工提供了依据。

The paper introduces the traffic organization in traffic and time-sharing and segmentation scheme, analyzes the stressed performance and widening horizontal distribution coefficient of the bridge by the finite element analysis model by taking some forecast small box girder？ s wide-ning project, so as to provide some reference for the widening construction of the forecast small box girder.
