摘要
Abstract
There are some information problems between priori and posteriori sample’s number according to the Bayes inference method for geotechnical parameters. When solving the engineering problems,the acquisition of priori and posteriori distribution is determined by the number of the sample,and the project fee must be paid while getting the sample number. The simplified Bayesian inference method has been put to apply to analyzing the priori and posteriori sample number of geotechnical parameters. According to the analysis of geotechnical parameters,the conclusion has been gotten as following. The calculated er-ror of statistical parameters’ mean and variance is minimum when the number of priori sam-ples and posteriori samples reaches to 30~50 and posteriori sample number is no less than 4 . This dissertation provides references for the determination of geotechnical engineering mechanics parameters of sample number of probability and statistics.关键词
