Yanghe Bridge Safety Testing And Evaluation

In view of the bridge as a transport hub in the national production plays more and more important role in life,the quality and safety of Bridges and caught the attention of the wider life and the safety of the bridge detection and evaluation of an effective safeguard measures.Bridge for the safety evaluation of the Bridges,through a series of parameters measurement,multi-disciplinary,multi-angle study Bridges safety performance,based on the real-time detection in the process of concrete bridge actual operation,by specific mathematical method to establish model,and the force of the bridge,the experimental method is mainly through the static load and dynamic load test,finally it is concluded that the overall safety evaluation of bridge.Paper main work is as follows:1)The collection,research and analysis of bridge accidents at home and abroad and the Bridges safety evaluation and other aspects of the relevant data,summarizing predecessors' work,from related disciplines theory,combining with laboratory test,systems analysis,according to the existing conditions to determine the final test plan;2)Telecting typical bridge for concrete strength,carbonization depth and steel bar corrosion degree,bridge of reinforced protective layer thickness,natural vibration characteristics and fracture measuring field detection;3)To select the reasonable calculation method of fuzzy mathematics to establish a reasonable calculation model,determine the weight of index parameters,and through the existing data for testing,get realistic reasonable weight value;4)Will be measured data entry the established model,the calculated bridge appearance performance evaluation;5)Through the establishment of mathematical model,the force of the bridge to experiment,the experimental method is mainly through the static load and dynamic load test,concluded that the stress distribution in the practical work of bridge;6)Comprehensive analysis it is concluded that the overall performance and safety assessment,to provide guidance for the safe operation of the bridge,to ensure property safety in the country and its people,maintain the social stability of bridge around and create good ecological environment is of great significance.
