摘　　要：本文结合武汉市中心的某办公大楼工程,针对深基坑地下连续墙叠合地下室外墙提出了一种安拆方便的单侧模板支撑体系,采用ANSYS软件对不同混凝土浇筑速度下单侧模支撑体系进行了研究,确定了该支撑体系的强度、变形和稳定性与浇筑速度的关系。选取混凝土浇筑速度为2.5m/h的情况,对单侧模板支撑体系及其支撑楼板进行了有限元分析并通过现场试验验证了该支撑体系的可行性。In this paper, a single side formwork support system is put forward for the wall of deep foundation pit and the wall of the basement wall combined with an office building in downtown Wuhan. The ANSYS software is used to carry out the research on the support system of the single side undei different concrete casting speed and the relationship between the strength, deformation and stability of the support system and the casting speed is determined. Selection of concrete casting speed for 2.5m/h, the finite element analysis was carried out on the single side formwork support system and its supporting floor, and the feasibility of the support system was verified by field experiments.
