带挑梁的整体桥面板拓宽提载技术研究与应用

Research and application of integral bridge deck widening and increasing load technology with cantilevered beams

从经济节约及结构可行性等方面综合考虑采用带钢筋混凝土悬臂挑梁的整体式桥面板对篁碧老桥进行拓宽提载改造,使得桥梁的技术标准得到提高,达到了理想的效果。

Starting from aspects of economy saving and structural feasibility,it decides to widen and increase the load of the old Huangbi Bridge by using steel reinforced concrete cantilevered beams integral bridge deck.As a matter of fact,it improves the technical criteria of the bridge,and achieves ideal effect.
