舟山小干二桥悬索跨主桥成桥荷载试验

Load Test of Completed Bridge for Main Suspension Span Bridge of Xiaogan No.2 Bridge in Zhoushan

舟山小干二桥悬索跨属于双塔双缆面自锚式悬索桥,主桥最大跨径370m,属同类型桥梁中世界第一。采用有限元软件对小干二桥悬索跨主桥进行模拟计算,按5个静载试验工况和2个动载试验项目组织对其进行成桥荷载试验。试验结果表明,小干二桥悬索跨主桥成桥质量良好、满足城A荷载等级标准。

The suspension span of Xiaogan No.2 Bridge in Zhoushan is a self anchored suspension bridge with double pylons and double cable plans.The maximum span of the main bridge is 370 m,which is the first of its kind in the world.The finite element software is used to simulate the suspension span of Xiaogan No.2 Bridge,five static load test conditions and two dynamic load test items are adopted and implemented in the load test of completed bridge.The test results show that the completion quality of the main suspension span bridge of Xiaogan No.2 Bridge is good and meets Cheng-A grade standard.
