基于有限元模型的和平路高架桥转体施工配重选择

Counterweight Selection of Heping Road Overpass with Swing Construction Based on FEM(Finite Element Model)

和平路高架桥为不等跨的钢结构连续箱梁桥,采用转体施工法时存在倾覆力矩。建立了有限元模型并采用三种配重方法对其进行计算,比较选择最优的配重方法,从而使得转体施工顺利进行,同时希望对类似工程有借鉴价值.

Heping road overpass is a continuous steel box girder bridge with unequal spans.There is an overturning moment when the swivel construction method is used.A finite element model was established and was calculated using three counterweight methods to compare and choose the optimal method,so that the turning construction can be carried out smoothly.At the same time,it is hoped that it can be used as a reference for similar projects.
