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.
