摘要
针对东海大桥主跨420 m的钢混凝土箱形结合梁斜拉桥中一片主梁进行了工艺试验研究,分析了混凝土的预应力和内力均在变化的特殊性;同时,对结构的应力、应变进行了检测.
This paper presents the process experimental study of one main beam of the steel-concrete composite box girder of 420-m cable-stayed main span of east china sea bridge. It focuses on demonstrating special characteristic of prestress and inside dint of the concrete, At the same time, the stress and deformation to the beam construction is examined.
