摘要
针对斜拉桥钢拱塔竖转施工过程中出现的拱脚位移和应力过大问题,以武汉高新二路独塔斜拉桥为研究背景,提出了一种斜拉桥钢拱塔竖向转体变形控制装置——稳定索,并通过有限元分析软件ANSYS分别对稳定索的安放位置、稳定索拉力大小的选取及稳定索释放对钢拱塔稳定性的影响进行了计算分析,最后通过监测数据进一步验证了该变形控制装置的技术合理性。
Based on the single tower cable-stayed bridge on the Gaoxin 2nd Road in Wuhan, a deformation control device is proposed to solve the problem of displacement and stress of arch springing in the vertical rotation construction of the tower of cable-stayed bridge. The location and cable force and the impact to the tower stability from the release of stable cable are computed and analyzed by the FEM software ANSYS. Finally, the technical rationality of the stable cable is verified by monitoring data.
