以某钢管混凝土拱桥为研究对象,采用MIDAS有限元分析程序,建立了该桥的空间有限元计算模型,计算了该桥的稳定安全系数,对其失稳特征进行了分析,根据分析结果,导出提高其稳定性的措施。
Taking a CFST arch bridge as the research object, the finite element analysis model of the bridge was established by using MIDAS finite element analysis program. The stability safety factor of the bridge was calculated and its instability characteristics were analyzed. According to the analysis results, Measures to improve its stability.
