摘要
对于单箱多室梁桥,采用传统的简化计算方法无法揭示出冲击作用下底板的真实受力情况,也就无法对相关病害做出准确分析。通过建立三维有限元仿真计算模型,得出底板的应力分布情况,其结论可为同类桥梁养护及设计提供参考。
As for the single box and multi-cell girder bridge with impact action, the practical strain of bottom plate cannot be reflected by traditional simplified calculation, and then the related distresses cannot be analyzed accurately. Establishing a three-dimensional finite element simulation model can help draw out the stress distri- bution of bottom plate, the conclusions of which could be used as references for maintenance and design of simi- lar bridges.
