The Study On The Feature Of The Random Field Of Soil Parameter And The Best Estimation

This paper looks soil as homogeneous stationary random fields , expatiates the application of the random process in the geotechnical engineering and establishes the basic concept , its assortment and digital feature of random process and random fields, tests whether this random fields is a stationary process and whether it is ergodic, applies correlation function theory and variable function theory in the study of the random fields of soil parameter, acquires the relation of the two theories and draws the conclusion that they are equal essentially, fits the measured curve by using the correlation function method , variable function method and other methods ,and acquires the value of correlation distance, applies the random fields theory of soil parameter in actual engineering, estimates the value of elevation and other soil parameters of 92 holes in Baoding City and the results are satisfying.
