The probabilistic model of rock and soil mechanics parameters affects the results and precision of reliability analysis and design. Based on testing data and some groups of prior distribution data (existing in history) in the same zone
this paper discusses the problem of how to estimate the distribution of rock and soil mechanical parameters for a small sample in the case of insufficient data. A multiple sources information fusion method based on Bayesian statistics theory is presented. Confirming the weight of every prior distribution by calculating the difference between its prior data and testing data
this paper brings about the optimum fitting of probabilistic model of rock and soil mechanical parameters.
