基于不同规范连续梁桥设计条件对比分析

Comparative analysis on continuous bridge design conditions based on various norms

以采用顶推施工的预应力混凝土连续梁桥为研究对象,通过建桥材料、作用选取及作用效应计算结果等方面的对比分析,探讨了新、旧规范设计参数之间的差异,为旧桥加固改造积累经验。

Taking the prestressed continuous concrete bridge with jacking construction as the research object, through comparatively analyzing bridge materials, function selection, effect and calculation results and other aspects, the paper explores the difference between new and old de- sign parameters, which has accumulated experience for old bridge transformation.
