Durability Evaluation System And Application Municipal Bridges

With the rapid development of China's economy, China's transportation industry has also been rapid development. As the main channel of transportation, the bridge has become very important. During construction and operation of bridge of a variety of evaluation in order to protect the bridge safety, especially in the aging state of the bridge, after long-term use and not timely maintenance and repair, bridge inevitably produce different degrees of disease affecting the durability, and reduce the service life of the component may eventually cause the collapse of the bridge. Bridge plays an important role in real life, not only to solve the problem of people across the river, mountains and rivers in a certain extent also contributed to the rapid development of China's economy.The assessment of durability of existing bridges has become an urgent problem to be solved. In order to be able to find the disease of existing bridges, and to take timely measures to repair and strengthen the service life of the bridge to reduce the incidence of accidents. Through investigation and Research on the existing bridges is proposed to evaluate the durability of the reinforced concrete bridge architecture diagram, and through Excel hierarchy analysis method, the durability of a bridge example of system analysis and research to determine the existing bridges of security risks. I hope to reduce the bridge due to the potential hazard has not been found timely through the analysis method of collapse accident. This article is divided into the following aspects:1. Refer to the relevant literature to understand the process and function of the Excel analytic hierarchy process, studies and masters the steps of the analytic hierarchy process. At the same time to understand the use of an example of a bridge now, through the method of questionnaire survey to obtain the required data.2. In the process of research and analysis, not only the general influence factors that the former researchers usually considered, but also the influence factors which were not considered.3. Through the excel level for an example bridge analysis method, combined with the final assessment results to determine the existing bridges of security risks, then this method is applied to analyze other bridges above to advance in the prevention of bridge accidents occur.
