摘　　要：目前有关高支模的国家规范尚未正式颁布,在高支模的设计和施工方面还没有一个统一的标准,导致高支模施工坍塌事故时有发生。分析高大模板支架的定义、荷载组合、计算模式、试验研究、节点半刚性和初始缺陷以及体系的可靠度等方面的研究现状,进一步理清对高支模开展研究的思路,提出一系列亟待解决的问题,为后续开展此方面的研究指明方向,同时也为相关规范(规程)的编制奠定基础。National standard of tall falsework has been not officially promulgated at present, and there is not an unified standard in design and construction of a tall falsework, which causes tall falsework to collapse sometimes. It is analyzed that the present conditions of the definition of tall falsework, load combination, calculation model, study on test, semi-rigid joint, initial defects and degree of reliability of system etc. And further the ideas of research on the tall falsework are rationalized. It is proposed a series of problems that must be solved urgently, which points out the direction of follow-up researches on this subject and lays the foundation for compiling relevant specifications.
