- Abstract:
- In order to study the difference and applicability of the technical condition evaluation methods of city bridges and highway bridges, comparison analysis of the evaluation methods among Technical Code of Maintenance for City Bridge (CJJ 99—2003), Code for Maintenance of Highway Bridges and Culverts (JTG H11—2004), Standards for Technical Condition Evaluation of Highway Bridges (JTG/T H21—2011) and Technical Standard of Maintenance for City Bridge (CJJ 99—2017) were carried out. Firstly, the basic theories and implementation methods for different bridge technique condition evaluation methods of specifications were completed. Secondly, comparison analysis on standard type, assessment method, assessment process, disease classification, assessment level and grade, applicability, advantages and disadvantages of several evaluation methods were analyzed, and the comparative study on the different applications in various types of bridges was done. Finally, some improvement suggestions for different assessment methods were put forward combined with the application situations. The results show that all of the city and highway evaluation methods adopt the comprehensive evaluation method, the evaluation methods play an important role in the industry of bridge condition assessment and maintenance management, but have certain differences in the theoretical structure, calculation model, evaluation method, evaluation standard, hierarchy and actual assessment application, each method has its applicability, advantages and disadvantages, different methods should learn and apply from each other in the use process. According to the practical application problems, relevant measures which include source of bridge diseases, specific implementation details of evaluation, information technology and intelligent evaluation should be improved and perfected.
