摘要
随着预应力混凝土梁桥的迅速发展,桥梁收缩和徐变影响的分析、计算成为设计、施工、监控越来越关心的问题。该文以某独塔单跨悬吊自锚式悬索桥方案为例,进行结构成桥后的收缩徐变效应分析,研究混凝土收缩徐变效应对结构的影响。
With the fast development of the pre-stressed concrete beam bridge, the analysis and the calculation of the bridge shrinkage and creep influence become more concerned problems in the design, construction and monitor. Taking the scheme of a single-pylon single-span suspended self-anchored suspension bridge as an example, the article analyzes the shrinkage creep effect after the bridge completion and studies the influence of the concrete shrinkage creep effect on the structure.
