摘要
为分析景观拱塔的强度和稳定性、钢混结合段和地锚梁的受力特点。文中以某拱塔景观斜拉桥为依托,采用Midas空间杆系有限元模型和Ansys实体有限元模型进行分析。研究分析得出,拱塔在裸塔阶段的强度和稳定性有较高的安全储备;钢混结合段受力较小,确定相应的构造措施;地锚梁需要设置一定数量的凸榫来抵抗水平力。研究成果对今后类似工程提供一定的参考。
The purpose of this article is to analyze the strength and stability of landscape arch towers,as well as the stress characteristics of steel concrete composite sections and anchor beams.Numerical analysis of a certain arch tower landscape cable-stayed bridge is carried out by using Midas spatial member finite element model and Ansys solid finite element model.The results shows that the strength and stability of the arch tower during the bare tower stage have a high safety reserve.The stress on the steel concrete joint section is relatively small,and corresponding structural measures have been determined.The anchor beam needs to be equipped with a certain number of tenons to resist horizontal forces.The research may provide a certain reference for similar projects in the future.
