| 摘 要： | 拓宽加固综合设计法就是采用拓宽的方法来提高桥梁的荷载等级,通过利用空间有限元法分析双侧拓宽加固时,边梁刚度对全桥承载力的影响,以选择合理的边梁刚度,可供旧桥改造时参考.

| Abstract: | The synthetic design procedures for used bridge flaring and strengthening is to heighten the load-bearing grade.The effect of edge beams rigidity on bearing capacity of whole bridge ought to be taken into account as analysing the bilateral flaring and strengthening in order to select rational rigidity of edge beams,which would provide reference for used bridge reformation. |
