摘　　要：文章利用有限元软件Midas Fea模拟了矮塔斜拉桥在塔梁同步施工工艺下塔梁固结部位局部实体模型,并与典型施工阶段下整体计算模型和施工监控实测数据进行了对比,分析总结了采用塔梁同步施工工艺的矮塔斜拉桥,在不同施工阶段塔梁固结部位的截面应力变化规律。This paper uses finite element software Midas Fea to simulate the local solid model of the tower-beam consolidation part of the extradosed cable-stayed bridge under the tower-beam synchronous construction technology,and compares it with the overall calculation model and the construction monitoring data under the typical construction stage.The section stress variation law of the tower-beam consolidation part of the extradosed cable-stayed bridge with tower-beam synchronous construction technology at different construction stages is analyzed and summarized.
