The article shows that the use of the normal distribution for statistical processing of the results of mechanical testing of soils, in particular, when determining the bearing capacity of piles in terms of soil, can lead, in case of a small number of tests and the presence of outliers in the experimental data, to an illegal underestimation of the calculated indicator to values less than the minimum values obtained in the tests performed. It is proposed to replace this distribution with a lognormal one that allows avoiding “implausible” conclusions.

使用对数正态分布处理桩基测土结果

文章表明，使用正态分布对土体力学试验结果进行统计处理，特别是在确定桩基土的承载力时，在试验次数少且实验数据中存在异常值，非法低估计算的指标，使其值小于在执行的测试中获得的最小值。建议用对数正态分布替换该分布，以避免“难以置信”的结论。
