Study On Detection And Evaluation Of Yangliu River Bridge On Jianguo South Road In Anshan

With the rapid development of social economy, large projects start throughout the country and logistics grow vigorously which lead to the increasing of heavy vehicles, traffic volume and the load of highway bridges. All kinds of abrasions of bridges will be watched after they have been used for years. Therefore, detection and evaluation of bridges have become one important guarantee that ensures safety maintenance and normal use of it. Bridge detection can not only reflects bridge’s situation, evaluate bridge’s bearing capacity exactly, and provide instruction for the safety of bridge service, but also provide technological bases for reinforce and maintenance of bridges. Based on this, Yangliu River Bridge on Jianguo South Road in Anshan is selected as a sample to detect the load and evaluate the bearing capacity. Some reinforce suggestion was given to provide reference for bridges detection of this kind.The main content is as follows:Firstly, bridge detection content and relevant theories were introduced. At present, there are two ways to evaluate bridge’s bearing capacity. One is technical states of structures detection and the other one is loading test evaluation.Secondly, for the bridge selected by the paper, appearance inspection and nondestructive test process of the bridge were described. Test dimension was summarized and based on which existing technical states of the bridge were evaluated.Thirdly, for the bridge selected by the paper, static and dynamic load test on the bridge were introduced, including exposition of test contents, instruments selection and test procedure. Then results on static and dynamic load test were analyzed and the bridge’s bearing capacity was evaluated.Lastly, according to test contents, bearing capacity of the bridge’s structure was checked, detailed process of checking calculation was presented and results on checking calculation of bridge’s bearing capacity were evaluated.
