Bearing Capacity of Reinforced Concrete Simple Beam Bridge Inspection and Analysis
According to the recent series of bridge collapse ,and points out the importance of safety testing and bearing capacity evaluating of the bridge in active service. RC simple beam bridge occupies a considerable proportion of the existing bridge in China, this paper discussed the commonly used inspection methods and its advantages and disadvantages, and draw a conclusion that load test method is the most commonly used and the most reliable way.Then, take “Ren jia dam bridge”bearing capacity inspection test as a example ,which in the “5.12 earthquake” disaster areas JiangYou ,MianYang.Discusses the whole prosess of bearing capacity calculation and field inspection in detailed.Compares the calculation results with the field inspection,the bearing capacity of the bridge meets the requirements of passing through "80t" vehicle loads, although is strongly impacted by the seismic force.
