摘要

为了掌握曲塔空间索面混合梁斜拉桥成桥时的工作状况,判断桥梁的实际工作状况是否满足设计要求,采用Midas Civil空间有限元软件进行仿真模拟,结合荷载试验研究了桥梁结构的静力效应(应变、挠度、裂缝宽度、索力)和动力效应(模态参数、冲击系数).结果表明该桥的正常使用状态和承载能力符合设计要求,为桥梁投入使用和后期运营养护提供了依据.

Abstract

In order to master the working condition of the cable-stayed bridge with space cable plane,composite beam and curved tower,and judge whether the actual working condition of the bridge meets the design requirements,the spatial finite element software named Midas Civil was used for simulation.The static effect(strain,deflection,crack width,cable force)and dynamic effect(modal parameter,impact coefficient)of bridge structure were studied combined with load test.The results indicate that the normal use status and bearing capacity of the bridge meet the design requirements,providing a basis for the bridge's operation and maintenance in the later stage.
