摘　　要：针对复杂劲性混凝土梁柱节点这一逆作法施工中的难点问题,结合工程实例,从前期模拟、施工工艺和质量控制等方面进行了研究。在对比分析了梁柱节点的几种连接形式后,对薄弱环节增加了施工措施,取得了不错的效果,相关经验对于其他逆作深基坑项目有一定的借鉴意义。In view of the difficult problems of complex stiff concrete beam-column joints in reverse construction, combined with engineering examples, it is studied from the aspects of pre-simulation, construction technology and quality control. After comparing and analyzing several connection forms of beam-column joints, construction measures are added to weak areas, and good results have been achieved. The relevant experience has certain reference significance for other reverse deep foundation pit projects.
