摘要
文章介绍了自助抽样法的基本步骤并以工程实例说明了基于少量岩土数据所得平均值、方差的不准确性,并简单有效的量化上述的不确定性,这对相关岩土设计分析的可靠程度的评价上有很大帮助。
This paper introduces the basic idea of bootstrapping and use it to a case history to illustrate the inaccuracy of the mean and variance estimated from limited geotechnical data.Moreover,using the bootstrapping,the statistical uncertainty associated with the estimated mean and variance are effectively quantified.This is important to evaluate the reliability of relevant design or analysis.
