通过对混凝土试件的承压试验,探索混凝土试件的徐变和收缩规律。通过对试验数据的分析与反复拟合尝试,找出系数稳定且相关度很高的初等函数表达式。
Through the pressure test of concrete specimens, the creep and shrinkage rules of concrete specimens are explored. Through the analysis of experimental data and repeated fitting attempts, we find out the elementary function expression with stable coefficient and high correlation.
