摘要
通过对桥梁定期检查,总结桥梁伸缩缝装置常见病害,并进行原因分析,提出了中小简支梁桥桥台部位取消伸缩缝、改善行车舒服性,分析了取消伸缩缝后桥梁变形实现的原理,并提出了关键施工工艺要点,工程实例证明半整体无缝式中小简支梁桥结构安全可靠,对工程实践有一定的借鉴价值。
Through the periodic inspection of the bridge,the paper summarizes the common diseases of the bridge expansion joints and analyzes the causes of the deformation of the bridge after eliminating the expansion joints,and puts forward the principle of eliminating the expansion joints of the bridge platform of the small and medium,and the key points of the key construction technology are put forward.The engineering examples show that the structure of the semi-integral small and medium-sized simply supported beam bridge is safe and reliable,and it has certain reference value for engineering practice.
