| 摘 要： | 针对目前国内桥梁水下结构安全性评定中存在的一些问题,在分析桥梁水下结构病害成因的基础上,将桥梁水下结构病害分为基础冲刷病害、基础变形病害、混凝土表面病害及其他病害四类;结合实际桥梁水下结构评定工作中的检测数据,综合考虑了《公路桥梁技术状况评定标准》（JTG/T H21-2011）中的评定指标,得出了评定指标各标度的评定标准,研究结果对现有的桥梁结构评估体系提供了有益补充并为后续的桥梁结构安全性评估奠定了基础。

| Abstract: | At present,many problems exist on safety evaluation of bridge underwater structure. In order to solve these problems,bridge underwater structure’s diseases are classified with foundation scouring,foundation deformation,concrete surface disease and other diseases after the analyses of the reasons. Combined with some practice data of bridge underwater structures evaluation and considering evaluation index of 《Standards for Technical condition Evaluation of Highway Bridges》（ JTG/T H21-2011）,the classified evaluation standard are obtained. The research results can improve the existing evaluation system and lay a good foundation on subsequent bridge structure’s safety evaluation. |
