大跨度预应力连续钢构桥声波CT技术检测研究

本文介绍了用声波CT技术检测大跨度预应力连续钢构桥的一种方法,并以芙蓉江特大桥主桥为例,将主桥分为9个检测段,在每个检测段的顶板、底板、左右腹板布置了四个剖面对全桥进行混凝土整体浇筑质量检测。检测结果表明,检测区段内整体浇筑均匀性较好,各检测区内混凝土基本满足设计的要求,但在桥梁混凝土结构局部出现低强度异常区,建议进行妥善处理。

Acoustic CT Technology Detection on Long-Span Prestressed Continuous Rigid Bridge

Taking the main bridge of Furong River Bridge as an example, the author of this paper describes acoustic CT technique detection of long-span prestressed continuous rigid bridge. The main bridge is divided into nine detection sections, and the four profiles of each detection segments (roof, bottom, left and right web) are laid out to test the overall quality of the full-bridge concrete pouring. The results shows that overall casting in each detection section is in uniformity, the concrete within the detectio...
