Abstract


With the increase in the useful life of the bridge , a growing number of bridges due to various reasons, there are security risks , serious threat to people 's lives and cause significant economic losses . To ensure the safe operation of the bridge structure , it must be effective and integrated detection and state evaluation , assessment of the current health status of a bridge , using scientific methods for detection and assessment of the bridge is particularly necessary . Based on this identification with the bridge work status , in time for the bridge management, repair , maintenance and reinforcement to provide reliable scientific basis to ensure that the bridge can be normal , safe operation , ensure that the road network can maintain a high level of service , play a greater economic and social benefits. Changsha, a paper based on the detection result of the reinforced concrete bridge , at the conclusion abroad on bridge safety evaluation method based on the use of \method, the assessment of the working state of the bridge , and the assessment of the existing methods were compared . By comparison examples , summarize the advantages and disadvantages of these methods . Main tasks include the following aspects: ( 1 ) According to bridge testing situation , hierarchical model to build bridges with the requirements of each component AHP weights contrast \weights obtained more objectively reflect the use of the various components of the bridge . ( 2 ) based on the detection result of the bridge , with a fuzzy comprehensive evaluation method , combined with \comparison, comparing the differences between them . ( 3 ) using fuzzy comprehensive evaluation method, combining AHP weights obtained and the \( 4 ) using a fuzzy comprehensive evaluation method and multi- level fuzzy comprehensive evaluation method to assess the bridge to compare the pros and cons between them .
