摘要
文章以某变截面连续箱梁桥为例,通过动静载试验,模拟桥梁在设计荷载作用下,承载能力是否满足设计要求。试验结果表明:该桥在动静载试验作用下处于弹性工作状态,未表现出明显的塑性变形,试验桥跨结构刚度及整体受力性能满足原设计要求,整体承载力满足原设计荷载等级“城市-A级”标准,符合设计荷载要求。
Taking the continuous box girder with variable section as an example,the load-bearing capacity of the bridge under the design load is simulated by dynamic and static load test.The results show that the bridge is in elastic working state under the action of dynamic and static load test,the results do not show significant plastic deformation.The stiffness and overall mechanical performance of the test bridge span meet the original design requirements,the overall bearing capacity meets the original design load grade"city-A"standard and the design load requirements.
