| Abstract: | Based on the project of an overweight vehicle weighed 340 ton passing through Baishuigang First Bridge,considering the bearing capacity of an old stone arch bridge designed by conventional load rating cannot meet the requirement of passing through of an overweight vehicle,safety evaluation of the feasibility of an overweight vehicle passing through the bridge was performed.The overall stiffness and strength of the bridge was evaluated by static and dynamic load test on site.The bearing capacity of the bridg... |
