某沿海既有旧桥的检测及损伤评价

The detection and damage evaluation of a coastal existing old bridge

针对沿海某既有旧桥出现的质量问题,现场对桥面系、上部结构、下部结构、裂缝开裂情况、材料风化程度、混凝土强度、钢筋间距以及钢筋锈蚀情况进行了调查、检测,并依据上述调查、检测结果对该桥进行了BCI评价,并对其适修性进行了评价,为同类工程事故的处理提供了借鉴。

According to the quality problems of a coastal existing old bridge, this paper made the site investigation, detection to deck scene, su- perstructure, substructure, cracking situation, material weathering degree, concrete strength, reinforcement spacing, reinforcement corrosion sit- uation, and according to the survey and detection results made BCI evaluation to the bridge, and evaluated its repair ability, provided reference for similar engineering accidents treatment.
