摘要
介绍并分析新旧箱梁桥间不同的拼宽方法。以一个拼宽箱梁为例,选定合适的拼宽方法,对拼宽箱梁的荷载横向分布系数采用不同方法进行计算。通过与有限元结果比较得到接近该类桥梁的计算方法,对简化计算的结果处理提出建议。
This paper introduces and analyzes different methods of widening between the old and new box girder bridges.Taking a widened box girder as an example,suitable widening methods are selected;different calculation methods to load transverse distribution coefficient are made.Through comparing with the results of fi nite element calculation,the suitable calculation method for this kind of bridge is obtained,and the suggestions to the result processing of simplified calculation are recommended.
