双柱型花瓶墩系梁裂缝加固方法研究

Research on Strengthening Method of Beam Cracks in Double-Column Vase-Style Piers

针对某城市高架桥双柱型花瓶墩系梁的裂缝问题,根据实际情况制定了加固方案,并在此基础上对加固方案进行了详细的设计。通过有限元软件Ansys分析,明确了加固方案的合理性,同时根据规范分析了钢锚箱、锚固螺杆以及焊缝的受力状态。最后,总结了加固施工要点。

Aiming at the crack problem for the beam of the double-column vase-style pier of a city viaduct, the reinforcement scheme was formulated according to the actual situation. On this basis, the details of the reinforcement scheme were given. Through the analysis of the finite element software Ansys, the rationality of the reinforcement scheme was verified. Meanwhile, the stress state of the steel anchor box, the anchor screw and the weld was analyzed. Finally, the main points of strengthening construction were summarized.
