摘　　要：针对一扣件式钢管高支模架坍塌事故,介绍了现场调查及检测情况,在此基础上对其稳定性进行了分析。结果表明,钢管、扣件材料不合格和未按规范合理布置竖向及水平剪刀撑导致的稳定承载力不足是该高支模架坍塌的主要原因。Based on a collapse accident of high steel tubular formwork-support with couplers, this paper presents the investigation and inspection in situ. Moreover, emphatically analyzes the stability of the high steel tubular formwork-support with couplers. The results show that the collapse accident of the high steel tubular formworksupport with couplers were mainly caused by the unqualified materials of steel tubular and coupler and without reasonable setting vertical and horizontal bridging according to code.
