石家庄南绕城高速大跨钢-混凝土简支结合梁桥吊装安全分析

Hoisting safety analysis of Long-span steel-concrete Simply supportedcomposite beam bridgein shijiazhuang south belt expressway

以石家庄市南绕城高速公路大跨度钢-混凝土简支梁吊装施工为研究背景,从施工总体部署和吊装安全关键节点检算以及安全吊装技术3个方面进行了阐述,施工现场采取了文中所述的安全吊装施工技术和安全分析成果,使的吊装工程项目一直处于安全状态,取得了较好的效果,可为同类工程吊装安全施工做参考。

Taking the large-span steel-concrete simple-supported composite beam lifting construction of the South Belt Expressway in Shijiazhuang as the research background,the bridge lifting was analyzed from three aspects:(1)overall construction deployment,(2)lifting safety key node calculation,and(3)safe lifting technology,and then we apply the above analysis in the field.The application results show that the hoisting construction project has been in a safe state.The application results have achieved good results.It can be used as a reference for similar projects.
