摘要
拉萨河特大桥为五跨三连拱结构,主跨108 m,为单线Ⅰ级铁路桥梁。介绍该桥主拱拱脚的结构设计,并通过三维电测和光弹性模型试验对局部应力进行了分析。
Lhasa River Bridge, with a main span 108m, is a 5-span, 3-arch structure and is also a Grade Ⅰ single-track railway bridge. In this paper, the structural design of the arch springs of the main arches of the Bridge is presented, and local stress of the springs is analyzed by means of three-dimensional resistance strain gauging and photoelastic model tests as well.
