摘　　要：基于有限元模型,以南京至句容城际轨道交通工程K7+489.09至侯家塘站区间(45+3×80+45)m连续刚构为研究背景,计算分析了不同合龙顺序对主梁应力、结构竖向位移以及主墩应力、位移的影响,由此进行合龙顺序的优化分析。Based on the finite element model and taking the(45+3×80+45)m continuous rigid frame of Nanjing Jurong intercity rail transit project K7+489.09 to Houjiatang station as the research background.This paper calculates and analyzes the effects of different closure sequences on the stress of the main beam,the vertical displacement of the structure and the stress and displacement of the main pier,so as to optimize the closure sequence.

关 键 词：多跨连续刚构 合龙顺序 位移 应力
