回弹法检测砌筑砂浆抗压强度技术规程

A.seq附录公式3）式中：r——回归方程式的强度平均相对误差（％），精确至0.1；er——回归方程式的强度相对标准差（％），精确至0.1；——由第i组砌体砂浆试块抗压试验得出的砂浆强度值，精确至0.1MPa；——对应于第i组试n——制定回归方程式的砌体数。专用测强曲线的强度误差应符合下列规定：平均相对误差r≤18.0％；相对标准差≤20.0％。当r和符合规定时，经专家论证通过后使用。

异常数据判断和处理异常数据判断依据GB/T4883，可采用格拉布斯准则进行异常值判断，将测区砂浆强度换算值按从小到大顺序排列、、……、，计算统计量： （E.seq附录公式\r11） （E.seq附录公式2）式中:、——格拉布斯检验统计量；——构件或检测批砂浆强度换算值的最小值；——构件或检测批砂浆强度换算值的最大值；、——格拉布斯检验临界值，按检测批测区数量由附录E查得。取检出水平为5％，剔除水平为1％，按双侧情形检验，检出水平对应临界值为，剔除水平对应临界值为。若>，且>，则判断为离群值，否则，判断没有离群值。对检出的离群值，若>，则判断为统计离群值，可考虑剔除，否则，判断未发现统计离群值，为歧离值。若>，且>，则判断为离群值，否则，判断没有离群值。对检出的离群值，若>，则判断为统计离群值，可考虑剔除，否则，判断未发现统计离群值，为歧离值。异常数据处理若检出了一个离群值，应用相同的检出水平和相同的规则，对除去已检出离群值后余下的数值继续检验，直到不能检出离群值为止。对除去已检出离群值后余下的数值，应按本文件第8.1条重新计算强度换算值的平均值、标准差和变异系数。检出的离群值总数不宜超过样本量的5％，若检出的离群值总数超过了这个上限，对此样本应作慎重的研究和处理。统计离群值可直接剔除，歧离值不得随意舍去，应尽可能寻找其技术或物理上的原因，若在技术上或物理上找到了产生它的原因，则应剔除或修正；若未找到产生它的物理上和技术上的原因，则不得
