摘要
依托某项目3-25m现浇预应力混凝土连续箱梁桥,应用有限元程序ANSYS建立花瓶墩三维实体模型,分析花瓶墩受力特点;进而与拉压杆模型计算得到的拉杆拉力进行比较。结果表明,采用拉压杆模型计算的拉杆拉力误差较小,可以满足工程要求,并作为花瓶墩拉杆设计的依据。
The thesis takes a 3 - 25m cast - in - place prestressed concrete continuous - box - girder bridge as an example, using finite element program ANSYS to build up the 3D entity model of the vase - shaped pier to analyze the loading features of it. The loading features will be compared with drawbar pull achieved from the strut - and - tie model calculation. The result shows that drawbar pull obtained from the strut - and - tie model calculation has relatively fewer errors, which will meet the requirements of the project as well as being the basis for the design of the vase - shaped piers.
