摘要
以某三跨等截面连续梁桥加固为例,通过比较现有各种旧桥加固方法,选择适合本桥加固的体外预应力加固方法。并通过实桥试验,分析加固后连续梁桥的受力性能,结果表明,本方法保证了结构安全可靠,满足了工程实际需要。
Taking the retrofit engineering of a three span continuous girder bridge as an example, the method of the external prestressing technique, which is suitable for the project, is selected by comparing all kinds of the reinforcement methods of the old bridges. Through the bridge test, the mechanical behavior of the continuous beam bridge is analyzed. The test results show that the structure is safe and reliable, which can meet the need of the engineering practice, and the reference is provided for the similar reinforcement project in the future.
