摘　　要：大体积混凝土梁浇筑施工过程中,难以避免由于体积过大出现的变形,进而造成梁下支撑的脚手架在搭设时,出现安全隐患和经济性差等问题。通过理论计算和有限元软件ANSYS模拟,结合工程实例,对叠合梁采取分两层浇筑的方式,确定合适的先浇高度,以改进搭设梁下支撑间距和缩短支撑拆除时间。During the construction of large-volume concrete beams,it is difficult to avoid the deformation due to the excessive volume,which will cause safety hazards and poor economic efficiency when erecting the scaffold supported under the beam.Through theoretical calculations and finite element software ANSYS simulation,and combined with engineering examples,the composite beam is poured in two layers to determine the appropriate first pouring height,improve the spacing between the supports under the erected beams and to shorten the support removal time.

关 键 词：叠合梁 先浇高度 支撑体系 支撑拆除
