摘要
利用midas/civil空间有限元分析,模拟余弦逐波顶升理论对简支变连续4×40 m T梁桥进行支座更换施工,通过对计算结果的内力、应力进行分析,验证了余弦逐波顶升支座更换理论是安全可行的,与整体同步顶升理论相比,更适用于山区高速公路桥梁的支座更换施工。
This paper use of Midas/civil space finite element analysis,for Simulating by cosine wave theory of lifting simply-supported continuous 4 × 40 m T girder bridge bearing replacement.Based on the calculation results of the internal force and stress analysis,the paper Verify the cosine wave by lifting support change theory is the safe and feasible,for the whole synchronization lifting than the theory.And it more suitable for the mountainous area highway bridge construction bearing replacement.
