摘要
昆山中环跨沪宁高速,采用顶推法施工,钢箱梁前设钢导梁,利用Midas Gen有限元软件分析在顶推施工中的最不利工况及内力值,并分别验算钢导梁压弯杆和轴心受压杆件的稳定性,为施工的顺利进行提供可靠保证。
Kunshan central link cross Shanghai-Nanjing highway adapts incremental launching method. Steel guide beam is set up in front of the steel box beam,uses finite element analysis software Midas Gen to analyse the most unfavorable conditions and internal force value of steel guide beam with incremental launching method,and checks the stability of the pressure-bending bar and the axis pressed bar of steel guide beam,provides a reliable guarantee for the construction smoothly.
