Abstract
Inversions of measurements of twelve Engineering Geophysical Penetration holes were done by the Weighted Least Squares method. The soil model was supposed consisting of sand, clay, water and air. The input error variances and the zone parameters were fixed by the feedback optimization method. The logs of the estimates of soil model parameters and their covariance matrix were determined. There are good correlations among the result logs along the profile. Paleo-soil layers can be recognized on the result logs.
