ZHAO Yu-fei, WANG Xiao-gang. Bayes optimization and fitting research of probability distribution of geotechnical strength parameters[J]. 2006, 27(S2).DOI:
the geotechnical strength parameters ( ) are very important
their values exert a great impact to the safety of the project. In previous analysis
those parameters ( ) were studied independently
so that the correlation between them is ignored. On the basis of geotechnical parameters submitting two-dimension normal distribution
the Bayes method to optimize the probability distribution is introduced. The coefficient of variability of the geotechnical parameters after optimization is reduced greatly; the feasibility of this method is proved by using the example of Jinping Hydropower station.
