摘要
自锚式悬索桥索梁锚固区域结构复杂,容易产生应力集中,研究锚固区域在索作用下的应力大小、分布十分重要。针对佛山平胜大桥吊杆锚箱进行足尺模型试验,得到索梁锚固区的应力状态、分布和传力途径,对自锚式悬索桥锚箱设计具有一定指导意义。
The hanger and girder anchor zone of the self-anchored suspension bridge is structurally complicated and is liable to the problem of stress concentration. It is therefore very important to study and have a good understanding of the stress amplitude and stress distribution of the anchor zone under action of hangers. In this paper, through the full-scale model tests for the anchor housings of hangers of Pingsheng Bridge in Foshan, a self-anchored suspension bridge, the stress conditions, stress distribution and stress transmitting path of the hanger and girder anchor zone of the Bridge have been obtained. The results of the study in the paper are of certain guidance to the design of anchor housings of other self-anchored suspension bridges.
