The possibility of using the methods developed in modern applied statistics for determining the lower confidence limit for the mathematical expectation of lognormal experimental values of a mechanical characteristic of soil, i.e. its ‘calculated value’, is studied. Practical considerations are given regarding the relative benefit of using the lognormal distribution in data processing as opposed to the normal distribution generally assumed for test results, especially with a small number of tests and real coefficients of variation.

对数正态分布在处理土壤力学测试结果中的应用

研究了使用现代应用统计学中开发的方法来确定对土壤力学特性的对数正态实验值（即其“计算值”）的数学期望的数学置信下限的可能性。给出了在数据处理中使用对数正态分布的相对好处的实践考虑，这与通常为测试结果假设的正态分布相反，尤其是在少量测试和真实变异系数的情况下。
