Abstract:The self-correlation of soil index and the calculation method of its characteristic parameter are discussed based on the random fields theory.The applicability of the calculation method of soil index relative distance and the determining principle of the calculation results are also discussed taking the specific penetration resistance p s of the cone penetration test(CPT) as an example.The representative value of relative distance of local area is obtained through calculation of a large amount of investigation data of real projects.
Keywords:soil index  random field  self correlation  relative distance
