Study on autocorrelation model and reduction function of variance of soil random field
The key to apply the random field theory to reliability is the confirmation of the reduction function of variance, which transforms the variable from ‘point characteristic to ‘space characteristic. A regular way is to choose the autocorrelation model from the experiment data, the reduction function of variance is deduced according to the autocorrelation function. The conventional reduction function of variance is modified based on the random field theory and CPT data of is an appropriate series for the analysis. A new autocorrelation model is brought forward and examples are analyzed to show the advantage of the new model, the results show that this model is adaptive with different autocorrelation function and the modified reduction function of variance is rational.
