Statistical Method for Random Field Model of Soil Profile in Geotechnical Foundation

Based on the paper （1）, this paper involves the revision of random field model of the soil profile in the geotechnical foundation and the statistical problems, such as the estimations of the mean function, the variance, the correlation distance, the domain of correlation area and so on. It also develops a new concept, the curve of equivalent correlation. The new concept make it effectual and convenient to determine the scale of correlationship finally.
