结合某高速公路体外预应力试验桥的设计,利用桥梁分析专业软件M IDA S/C iv il对该桥的钢索端部锚固区域进行了空间应力仿真分析,研究了关键区域的应力分布、受力特点。同时,基于分析结果,应用拉杆-压杆分析模型对该区域进行了相应的配筋设计,研究结论可供类似工程参考。 Combined with the design of an external prestressed test bridge for expressway, the space stress simulation analysis of the anchorage area of ​​the cable end of the bridge is carried out by the software M IDA S / C iv il of bridge analysis, and the stress distribution in the key area is studied. Force characteristics. At the same time, based on the analysis results, the corresponding reinforcement design of the area was carried out by using the rod-strut analysis model, and the conclusions of the study can be used for reference to similar projects.
