Probabilistic Distribution of Rock & Soil Parameters by Using Expert's Information Fusion Method

ZHANG Wei,LI Xi-bing,GONG Feng-qiang(School of Resources and Safety Engineering,Central South University,Changsha 410083,China)  
It is a hotspot to deduce the probabilistic distribution of rock soil mechanical parameters by a small sample.The expert's information fusion method is presented in this paper.Based on testing data and some groups of prior distribution data(existed in history) in the same zone,this paper discusses the problem how to estimate the distribution of rock soil parameters for a small sample in the case of insufficient data.Confirming the weight of every prior distribution by expert's marking to the difference between its prior data and testing data,this paper brings about the optimum fitting of probabilistic model of rock soil parameters.
