自锚式悬索桥桥式特点与发展初探

自锚式悬索桥是一种将主缆锚固在自身加劲梁上的桥式结构体系,近几年在国内外逐渐兴起。本文对自锚式悬索桥的历史、国内外发展情况进行概述;通过国内外研究资料,从材料,矢跨比、拱度、混凝土收缩徐变及非线性影响,总结分析此种结构体系的力学性能;论述了已建自锚式悬索桥的不同施工技术与方法以及需待解决的问题。

Preliminary Approach to Characteristics and Development of Self-Anchored Suspension Bridge Type

Self-anchored suspension bridge is a kind of bridge type structural systems that put main cable on self-stiffened beam. In recent years it rises gradually at home and abroad. The paper states briefly the history of self-anchored suspension bridge, the developing conditions at home and abroad. Through the studying data at home and abroad from material, ratio of rise to span, camber, shrinkage and creep of concrete as well as non-linear influence the paper summaries, analyzes the mechanics performance of this kind of structural systems. It also states the different construction technology and me-thod and the problem to be solved of the established self-anchored suspension bridge.
