摘　　要：文章以衡山路跨陇海立交桥第1联边跨、中跨受力最不利梁为工程研究案例,基于Midas Civil有限元软件对桥梁承载力进行检算分析,并介绍桥梁工程检算参数取值。通过Midas Civil建立桥梁模型,模拟桥梁结构和荷载,对比分析桥梁元结构的承载能力和桥梁实际承载能力,结果表明该桥梁结构满足规范荷载等级使用要求。研究可为同类型工程提供经验参考。Taking the beam with the least stress of the first side span and middle span of Longhaiinterchange of Hengshan road as the engineering research case,the analysis on the check and calculation on the bridge bearing capacity is made based on the Midas Civil finite element software,and the values of bridge engineering check and calculation parameters are introduced.The bridge structure and load are simulated by using Midas Civil to establish the bridge model,so as to compare and analyze the bearing capacity of the bridge element structure and the actual bearing capacity of the bridge.The results show that,the bridge structure meets the operating requirements of the standard load level.The research can provide empirical reference for similar projects.
