PClass-CPT Program introduction

Tthe PClass-CPT program© reads and displays the results of Cone Penetration Tests (CPT). The results are used in estimating soil types and properties at each depth increment, and classify the soil accordingly.

The Soil Classification method used in this program is based on the Probabilistic and Fuzzy Soil Classification from Cone Penetration Test developed by Dr. Zhongji Zhang and Dr. Mehmet T. Tumay
