【摘要】 借助Midas有限元软件,对霍河大桥合拢段进行了应力分析,结果显示大桥在边跨合拢和中跨合拢的应力集中是不同的。为了避免施工过程中桥墩受力超过承载能力极限,根据不同的施工段,制定了相应的安全施工方案和安全技术措施,以防止安全事故的发生。该研究对桥梁合拢段的安全施工可起到一定的指导作用。更多还原

【Abstract】 Based on Midas finite element software,this paper analyzes the stress of closure segment in Huo River Bridge.The results show that the stress concentration positions of side span closure segment and middle span closure segment are different.In order to avoid exceeding the carrying capacity limits during the construction,for different construction stages,the paper formulates corresponding safety construction scheme and safety technical measures to prevent accidents.The study is helpful for the safety construction of closure segment.更多还原
