| 摘 要： | 介绍了斜腿刚架拱桥微弯板的常见病害,并通过微弯板进行局部有限元应力分析,指出微弯板厚度过薄及拱片侧向刚度较弱是微弯板病害的主要原因.根据分析结果提出了斜腿刚架拱桥微弯板病害防治措施与对策,并用有限元分析证明措施的合理性.

| Abstract: | The common deteriorations of slabs with a slightly curved bottom are introduced.By analyzing local finite element stress,deteriorations of slabs are considered to be caused by the lack of slab thickness and arch-rib lateral stiffness.The methods for preventing further deteriorating and the maintaining strategies are proposed,which are validified by the finite element analysis. |
