高支模满堂支架系统在大中跨度现浇连续箱梁施工中普遍使用。为系统分析高支模碗扣式满堂支架应力与位移变化规律，依托实际工程，通过建立碗扣式满堂支架系统有限元模型，分析结构在各种不利荷载作用下的应力与位移值，并通过对施工过程中支架应力和位移值的实时监控来验证支架系统的安全稳定性及数值计算的可靠性。研究表明碗扣支架数值计算与实测最大应力和位移结果大致吻合，且均未超过规范允许值，碗扣支架刚度与稳定性满足施工要求。

High?supported and cuplock joint full framing system has been widely used in the field of large?middle span continuous casting box?beam bridge construction. In order to make a systematic analysis of the stress and displacement?changing rule in high?supported and cuplock joint full framing, this paper makes an analysis of stress and displacement value in structure under various adverse load,and verifies the stability and reliability of numerical calculation in framing system by real?time stress and displacement value monitoring during construction. The research shows that the numerical calculation of cuplock joint framing is not only generally in agreement with measured results of the maximum stress and displacement, but also both of them are under criterion value, and the rigidity and stability of cuplock joint framing meets the construction requirements.
