Abstract In the appendix Dof the Specification for Winter Construction of Building Engineering ,there are practical examples of concrete′s maturitymethod and the equi valentage method .Nevertheless,these are rather difficult to understand.Accordi ng to the simulation function and its constant for so—lutions,it is suggested to adopt the third power functi on formula to solvethem,and the adoption of equal strength coefficient method could be able togain the concrete strength by one step immedi ately .
Key words winter construction,maturity of concrete ,simulation functi onmethod
近年发布的《建筑工程冬期施工规程》(以下简称《规程》)附录D就成熟度法和等效龄期法的实际应用提供了说明和实例。由于说明将两种方法混合叙述,造成理解困难;在计算实例中未说明模拟函数的回归方法对推广应用有一定影响。此外两种方法依据试验数据回归强度龄期曲线时采用了指数函数带来了较大的误差,本文就上述问题进行较深入的分析,并对等效龄期法系数的求取提出修正的数据以及改进的方法———强度系数法。建议采用统一的数据以便使各种方法得到统一的数据,达到比较的目的。
