摘要
以一座四塔单索面矮塔斜拉桥为工程依托,从环境年平均相对湿度、加载龄期和运营时间上探讨了混凝土收缩徐变效应对主梁的影响;采用4种不同规范对比分析了收缩徐变效应对索力的影响,得出了收缩徐变效应对该类桥型受力性能的影响规律,为以后同类桥型的设计提供参考。
Based on the engineering of a low tower cable-stayed bridge with four-tower and single cable plane, this paper discussed the influence of concrete shrinkage creep effect on the main beam from environmental annual average relative humidity, loading age and operation time. Using four different specifications, it compared and analyzed the influence of shrinkage creep effect on cable force, and concluded the influence law of shrinkage creep effect on mechanical performance for this kind of bridge, which provided references for the design of the same kind of bridge in the future.
