Abstract

Predicting sand parameters such as Dr, Ko, and OCR from CPT measurements is an important and challenging task for the geotechnical engineer. In the present study, a system of neutral networks is developed for predicting these parameters based on CPT measurements. The proposed system uses backpropagation neural networks for function approximation and probabilistic neural networks for classification. By strategically combining both types of networks, the proposed system is able to predict accurately Dr, Ko, and OCR of sands from CPT measurements and other soil parameters. Details on the development of the proposed system are presented, along with comparisons of the results obtained by this system with existing methods.
