现有桥梁技术状况评定的差异性研究与实际应用

Research and Practical Application of Differences in Technical Condition Assessment of Existing Bridges

桥梁技术状况评定是综合评定桥梁技术状况的主要手段,针对我国现阶段实施的《城市桥梁养护技术标准》(CJJ 99—2017)和《公路桥梁技术状况评定标准》(JTG/T H21—2011)两本规范标准进行差异性研究,从多个维度展开分析,并结合典型工程实例进行应用研究,比较两本标准的差异性、适用性以及实际应用中的不同之处。

The assessment of bridge technical condition is the main basis of bridge management and maintenance.According to two standards of Urban Bridge Maintenance Technical Standard(CJJ99—2017)and Highway Bridge Technical Condition Assessment Standard(JTG/T H21—2011),the difference research is carried out,and the analysis is carried out from the multiple dimensions.Combined with the typical engineering examples,the differences and applicability of the two standards,and the differences in the practical application are compared.
