摘要
文章以箱形拱式旧桥为研究对象,以桥梁现行荷载标准与量测实际状况为计算依据,采用有限元分析软件Midas/Civil建立平面杆系模型,计算分析该旧桥结构现有承载能力,判定桥梁的安全工作状态。
With the old box-shaped arch bridge as the study object,and with the existing bridge loading standards and actual situation measurement as calculation basis, this article established the plane truss model by using the finite element analysis software Midas/Civil, calculated and analyzed the existing carrying capacity of this old bridge structure,and determined the safe operating state of the bridge.
