Estimation of compaction parameters of fine-grained soils in terms of compaction energy using artificial neural networks
(WILEY-BLACKWELL, 2011) Sivrikaya, Osman; Soycan, Taner Y.
The determination of the compaction parameters such as optimum water content (w(opt)) and maximum dry unit weight (gamma(dmax)) requires great efforts by applying the compaction testing procedure which is also time consuming and needs significant amount of work. Therefore, it seems more reasonable to use the indirect methods for estimating the compaction parameters. In recent years, the artificial neural network (ANN) modelling has gained an increasing interest and is also acquiring more popularity in geotechnical engineering applications. This study deals with the estimation of the compaction parameters for fine-grained soils based on compaction energy using ANN with the feed-forward back-propagation algorithm. In this study, the data including the results of the consistency tests, standard and modified Proctor tests, are collected from the literature and used in the analyses. The optimum structure of a network is determined for each ANN models. The analyses showed that the ANN models give quite reliable estimations in comparison with regression methods, thus they can be used as a reliable tool for the prediction of w(opt) and gamma(dmax).
