转体桥梁特征构件受力分析

Research on Mechanical Properties of Rotating Bridge'typical parts

转体施工因其独特的优越性,被广泛应用于斜拉桥平转施工之中,然而对斜拉桥平转阶段受力性能的研究很少。本文以绥芬河斜拉桥转体施工为例,针对转体桥梁的特征构件—转盘,采用解析法和有限元法对转盘进行受力分析,得出一些结论。

As a construction method, rotating construction is widely used in flat rotating of cable-stay bridge construction because of its unique advantages. But there is little research on force properties of flat rotating of cable-stay bridge construction. This article takes the Suifenhe＇ cable bridge rotating construction as an example, uses the analytical method and finite element method to study about the force performance of turntable with drawing some conclusion.
