Bridge is to ensure that roads and control of key positions,by the design standards,the use of age,construction quality and materials used,the conservation of quality, environmental erosion,traffic load changes and,occasionally,to improve levels of road accidents and other factors,the occurrence of the aging breakage, cracks,deformation and load-carrying capacity is too large to reduce such a phenomenon,leading to functional decline and even structural damage,not normal use. In order to provide safe,fast and comfortable travel conditions,and ensure the normal operation of the bridge, we must work on both bridges make a correct assessment of the state.At the conclusion of this article on the bridge to assess the current domestic and foreign research results,based on the work of the state of concrete girder bridge to carry out the assessment methods for further research. The paper described the assessment of the meaning of the bridge and the basic characteristics of the bridge method to assess the status of the Summary and Review. Through Xi Yu Highway testing of the more than 50 concrete girder bridge,summed up the bridge of the typical disease-prone, and a detailed analysis of the causes of these diseases. Thesis detail AHP model of the structure, ideas, and characteristics, and introduced the use of AHP and the basic steps, as well as the determination of the weight values. In addition, it discusses the basics of fuzzy set theory and fuzzy evaluation method and the basic steps. The use of the above-mentioned principle, in line with the existing information and relevant norms, the establishment of concrete bridge condition assessment model, and calculated the weight of all levels of the value of indicators, the use of fuzzy and qualitative description of the distribution method to establish the membership function of the underlying indicators, and concrete girder bridge to carry out a comprehensive assessment.The Shi Chuan He bridge, at Xi Yu Hiahway of Shan Xi province,was evaluated by the article describes the method,and the results indicated that the method of the existing concrete girder bridge to assess the status is feasible...
