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...
