EXTENDED BAYESIAN METHOD OF INVERSE ANALYSIS IN GEOENGINEERING
岩土工程反分析的扩展贝叶斯法

In the light of defect of the conventional Bayes method,a new inverse analysis method is discussed by using probability theory,statistical principle and modern information theory. With the matching coefficient b,site information is combined with previous information,so that the least square method,maximum likelihood method and Bayes method are unified in form. In addition,the best order of prediction model can be calculated by the quality and quantity of observed values. With the quantitative analyses on b,the weighted ratio between observed values and initial estimation values is obtained directly for given parameters.
