PC变截面空心板桥承载力评估及寿命预测

On loading capacity evaluation of hollow plate of PC variable cross-section and its lifespan prediction

根据国内外研究现状,结合依托工程桥梁检测结果,对旧桥承载力进行了总结和评估,在项目组已有的研究基础上,对PC变截面空心板使用寿命进行了研究,以便指导今后的设计、施工、养护。

According to the research survey at home and abroad, the paper combining with the inspection results of the engineering bridges, sums up and evaluates the loading capacity of old bridges, and researches the lifespan of the hollow plate of the PC variable cross-section based on the current research, so as to direct the future design, construction and maintenance.
