| 摘 要： | 对主跨径128m独塔单索面斜拉桥实施静载试验，在各加载工况下，测试并分析关键截面的主梁挠度、索力增量、主梁应力和主塔偏位等。通过比较该桥的实际加载效应和设计分析模型，结果表明：该桥的刚度和承载能力满足设计和使用要求；采用塔梁固结，辅助墩，多室箱梁的结构形式能有效的提高抗扭刚度。

| Abstract: | Static load experiments were carried on a single-tower,single-plane cable-stayed bridge with a main span of 128m at various load conditions.Loading effects of major cross-section,namly: deflection of the main beam,increment of cable force,stress of the main beam and the main tower,displacement of the main tower were measured and analyzed.By comparing the actual load effects with the design analysis model,results show that: the stiffness and load-bearing capacity of the bridge meet the design and use require... |
