摘要
以某钢筋混凝土预应力斜交T梁为工程背景,为了保证该桥在运营过程中的安全,对其进行静载检测,以此来确定该桥是否满足正常使用要求。本文采用有限元软件Midas/Civil对桥梁结构进行计算分析,然后与实际测量的挠度、应力和应变等进行对比分析,详细描述了静载检测与桥梁结构分析软件Midas/Civil相结合在此类型桥梁下的应用,为钢筋混凝土预应力斜交T梁试验提供参考。
Taking a reinforced concrete prestressed oblique T as the engineering background,in order to ensure the operational safety of the bridge,it is tested for static load to determine whether the bridge meets the normal use requirements. In this paper,the finite element software madis/civil is used to calculate and analyze the bridge structure,and then compared with the measured deflection,stress and strain. The static load detection and bridge structure analysis software Midas/Civil are combined in this type of bridge. The application provides a reference for the reinforced concrete prestressed oblique T-beam test.
