On the basis of field investigation and test data,the probabilistic characteristic values such as the average value,variable coefficient,relative distance of the shear strength index, c,φ ,and specific penetration resistance p s of static penetration tests of soil are analyzed and calculated with the probability statistics and random process theory.The study is not only a deeper exploration into the soil index itself,but also provides necessary technical parameters for the reliability analysis of geotechnical engineering and the determination of partial factors in foundation designs.
