以超长跨径RPC拱桥的设计为研究对象，对拱桥的结构设计参数进行了拟定，并通过有限元模型的建立，分析计算了拱桥的拱圈内力、拱圈截面强度、拱圈整体及局部稳定性，计算结果表明超大跨径RPC拱桥结构受力性能满足设计要求。%Taking super-long span RPC arch bridge design as the research target,the paper simulates the arch bridge structure design parame-ters. Through establishing finite element model,it analyzes and calculates internal arch bridge arch circle force,arch circle section strength,in-tegral arch circle and local stability. Results show that:the super-long span RPC structure stress performance meets design demands.
