兰青线峡下湟水河钢管混凝土拱桥静载试验分析

Static Load Test of Xiaxiahuangshui River Steel Pipe Concrete Arch Bridge at Lanqing Railway Line

对运营1a后的兰青线峡下湟水河的一座96m双跨下承式钢管混凝土系杆拱桥,进行了静载试验检测,观测试验荷载作用下结构内力/应力、变形/位移反应,以便评价该桥总体施工质量,鉴定该桥的承载能力,为工程的运营、养护和维修提供必要的参考资料,同时也从结构角度验证该类桥在使用上的合理性、受力上的优良性。

Static load tests of a 96 m twin spans under-supported steel pipe concrete tied arch bridge in Xiaxiahuangshui river have been carried on after its operation one year later. In the tests, structural internal force/stress, deformation/displacement response under the test load was measured in order to evaluate of the overall construction quality of the bridge and identify the carrying capacity of the bridge. It provides necessary reference for engineering operations and maintenance, and also tests and verifies such bridge rationality in use as well as good quality in bearing the load, from a structural point of view.
