摘　　要：梁板结构早拆模施工的截面承载力增长与混凝土强度增长关系为非线性关系,且早期承载力计算不宜直接按规范给定的方法进行计算。从限制塑性发展与不限制塑性发展的不同角度,对不同情况下承载力的发展情况进行研究,并对计算结果进行相应的分析,绘制出可直接查用的正截面承载力达设计值比率的曲线图表,可提供早拆模施工技术人员使用,或作相关研究参考。The correlation between carrying capacity and the growth of the strength of concrete beam slab was nonlinear at the early dismantling construction stage,and early bearing capacity calculation should not be directly according to the specification given calculation method.This paper from the limited development of plastic and non plastic development of different angle,conducts the research to the development situation of bearing capacity under different conditions,and the corresponding analysis on the calculation results,draw force curve chart design value ratio of normal section bearing can be directly used,can provide early dismantling construction technical personnel as a reference.
