摘 要:Standard Penetration Test(SPT) and Cone Penetration Test(CPT) are the most frequently used field tests to estimate soil parameters for geotechnical analysis and *** soil parameters are related to the SPT *** contrast,CPT is becoming more popular for site investigation and geotechnical *** of CPT data with SPT N-value is very beneficial since most of the field parameters are related to SPT N-values.A back-propagation artificial neural network(ANN) model was developed to predict the N6o-value from CPT *** used in this study consisted of 109 CPT-SPT pairs for sand,sandy silt,and silty sand *** ANN model input variables are:CPT tip resistance(qc),effective vertical stress(σ’v),and CPT sleeve friction(fs).A different set of SPT-CPT data was used to check the reliability of the developed ANN *** was shown that ANN model either under-predicted the N60-value by 7-16%or over-predicted it by 7-20%.It is concluded that back-propagation neural networks is a good tool to predict N60-value from CPT data with acceptable accuracy.
