摘要
本研究针对水麻高速公路上山区高墩简支转连续T形梁桥,通过建立有限元模型提出了纵向单点逐墩、横向同步顶升的支座更换新方法。仿真分析结果表明采用新方法更换支座,合理可行,结构安全也可得到保证,为同类桥型更换支座提供了一种新方法。
Aiming at the high piers simple supported-to-continuous T girder bridge on the Shuima Expressway in the mountain area, the new method of replacing bearings is put forward by finite element method. This method is called longitudinal single-point（followed by pier）, lateral synchronous jacking-up. The results of simulation anlysis show that the structural safety is assured by replacing the bearings using the new method, which provides one new method for the similar bridge bearing replacement.
