摘要
拉萨河特大桥主桥吊索锚固采用承拉式锚箱结构,介绍对该结构在钢管混凝土拱肋和混凝土梁内的锚固以及焊接锚箱本身进行的静动载试验,以检验其承载能力和抗疲劳性能是否满足设计要求。并通过试验研究对吊索锚固构造进行评价,提出改进意见或建议。
The hanger anchoring system for the main bridge of Lhasa River Bridge is designed as a type of tensile anchor housing structure. This paper presents the anchoring of the structure inside the concrete-filled steel tube arch rib and concrete girder, and the dynamic and static tests made for the welding of the structure itself in order to verify if its bearing capacity and fatigue performance can meet the design requirement. Through the test study, the structure of the anchoring system is evaluated and proposals for improvement of the system are made as well.
