A New Soil Classification Method Using Normalized CPT/CPTU Parameters Based on Modified Bayesian Model

Abstract

Soil classification results from CPT/CPTU always involve the uncertainty of correlation between mechanical behavior and soil composition. For better processing large quantities of tests data obtained form CPT/CPTU, Modified Bayesian model was introduced and corresponding soil classification method was proposed. The validity of the new method was verified through local silt samples. Evaluation results also suggested that the proposed new soil classification method had well applicability.
