摘要
受材料性能演化和运营荷载变化的影响,双塔双索面斜拉桥的拉索性能发生改变,进而影响桥梁的正常服役性能。为确保斜拉桥结构安全,及时更换不满足设计要求的拉索非常必要。基于此,文章以蚌埠市解放路淮河大桥为工程背景,基于桥梁斜拉索技术状况调查结果,从斜拉索技术状况、换索设计方案及换索设计要点三方面阐述了双塔双索面斜拉桥的换索设计方法。文章研究成果可为斜拉桥换索工程提供参考。
Due to the evolution of material properties and changes in operating loads,the cable performance of cable-stayed bridge with double towers and double cable planes changes,which in turn affects the normal service performance of the bridge.In order to ensure the structural safety of cable-stayed bridge,it is necessary to replace the cables that do not meet the design requirements in time.Based on this,this paper takes Huaihe River Bridge on Jiefang Road in Bengbu City as the engineering background to expound the cable replacement design method of the double-tower double-cable plane cable-stayed bridge from the technical status of the stayed-cable,the cable replacement design scheme,and the key cable replacement design points based on the survey results of the technical status of the bridge stayed-cable.The research results of this paper can provide reference for cable replacement engineering of cable-stayed bridge.
