Study of strata permeability classification and optimum partition methods

Cluster analysis and optimum partition methods are used for the classification of the stratum permeability based on the drilling data. The proposed methods of classification can be partially programmed for the data processing, which should be helpful to reduce the arbitrary errors of experience method used previously in the classification of soil strata. A river embankment example with 85 cross sections of drilling data was analyzed to show how to use the suggested steps to classify the soil strata. It verified the reliability of this method.
