Abstract: The two different methods for estimating the correlation distance of soil layers are compared and studied based on the random field theory. The reason why difference correlation distances may be estimated by different methods is explained. The results obtained by using both methods respectively are proved to be approximately the same if the number of samples is large enough. The correlation function method is improved in order to make the curve fitting and parameters determination easily. The conclusion is validated through calculation of some investigation data of practical engineering.

Key words: random field, correlation distance, correlation function, reduction function of variance
