对现役桥梁技术状况三种评定方法的对比分析

Comparative Analysis of Three Assessment Methods of Active Bridge Technology Condition

现役桥梁主要由《公路桥涵养护规范》《城市桥梁养护技术规范》和《公路桥梁技术状况评定标准》三部规范指导进行技术状况评定,为了研究三者的差异及各自的优缺点,对三部规范采用的评定原理、评定过程作了简要介绍,分析评定过程及结果,并作对比分析。结果表明:路桥涵养护规范的可操作性强,但评定结果受主观因素影响大;城市规范的优势在于从定量分析,但评分偏高;公路桥梁技术标准对评定过程中的诸多细节描述十分详细,但对病害严重程度的反映不够准确。研究结果可为桥梁管理养护工作提供参考。

The condition of active bridge was mainly assessed by code of maintenance of highway bridges, urban bridge maintenance technical standard and highway bridge technical condition evaluation standard, in order to analyze the differences and their respective advantages and disadvantages, the principles of assessment, assessment process made brief introduction, analysis of the process and results of the evaluation from three codes was analyzed and compared. The results showed thatcode for maintenance of highway bridges has strong operability, but evaluation of the influence of subjective factors to accuracy; The advantage of the urban bridge maintenance technical specifications is quantitative evaluation on the bridge technical condition, but high scores; highway bridge condition assessment standards on many of the details of the assessment process described in great detail, but reflect the severity of the disease is not accurate enough. The research results can provide reference for bridge management and maintenance work.
