Characteristic of the random field of geotechnical parameters and linear prediction

Some basic problems of geotechnical parameter are approached in this paper based on the theory of random field.There are two theories of half variant function and correlative function to describe the random field of geotechnical parameters.Their connotation is explained by theoretical analysis and derivation.There are some methods to calculate the correlative distance of the geotechnical parameters.It is certified that the weighted least square polynomial can be used in the optimum linear prediction.
