| 摘 要： | 根据预拌混凝土试件拔出力及抗压强度值的试验数据,利用最小二乘法,选取4种不同函数形式进行回归分析,推荐采用直线形式的回归方程作为唐山地区预拌混凝土后装拔出法地方测强曲线。通过验证性试验表明:利用提出的测强曲线进行检测,得到结果与混凝土实际强度相比,相对误差较小,检测精度高。

| Abstract: | Based on the data of pull-out force and compression strength of premixed concrete,the local curve of pull-out post-insert method in Tangshan was set up by using the least square theory.Compared with four different function forms,the line form is recommended for the local curve.The experimental results showed that the estimated concrete strength which is given by the local curve is close to true strength.The relative error of calculation value compared with experimental data is little. |
