Experimental Study on the Pore Water Pressure Generation Characteristics of Saturated Silty Sands

Predicting the Limit Void Ratios of Coarse-Grained Soils Using Artificial Neural Networks

“…Similarly, the emax values predicted by the ANN-2 model were compared with the emax values obtained from literature (Polito, 1999;Santamarina and Cho, 2001;Sukumaran and Ashmawy, 2003;Tika et al, 2003;Erzin, 2004;Park and Byerne, 2004;Cho et al, 2006;Bareither, 2008;Wichtmann and Triantafyllidis, 2013;Belkhatir, 2014;Oh, 2014;Bensoula et al, 2015;Salvatore et al, 2015;Erzin et al 2016) in Figs. 8 and 9, for training and testing samples, respectively.…”

“…The compiled data obtained from the literature (Polito, 1999;Santamarina and Cho, 2001;Sukumaran and Ashmawy, 2003;Tika et al, 2003;Erzin, 2004;Park and Byerne, 2004;Cho et al, 2006;Bareither, 2008;Wichtmann and Triantafyllidis, 2013;Belkhatir, 2014;Oh, 2014;Bensoula et al, 2015;Salvatore et al, 2015;Erzin et al 2016) to form a wider database were used to establish a predictive relationship between the limit void ratios (emax and emin ) of coarse-grained soils and their two graining parameters, namely, mean particle size (D50) and uniformity coefficient (Cu). The descriptive statistics of the data containing the graining parameters and limit void ratios of different 181 soils are given in Table 1.…”

“…ANN-1 and MR-1 for the prediction of the emin values of coarse-grained soils and ANN-2 and MR-2 for the prediction of the emax values of coarse-grained soils. The results predicted from the ANN and MR models were compared with the experimental results taken from the literature (Polito, 1999;Santamarina and Cho, 2001;Sukumaran and Ashmawy, 2003;Tika et al, 2003;Erzin, 2004;Park and Byerne, 2004;Cho et al, 2006;Bareither, 2008;Wichtmann and Triantafyllidis, 2013;Belkhatir, 2014;Oh, 2014;Bensoula et al, 2015;Salvatore et al, 2015;Erzin et al 2016). Moreover, different performance indices, namely, the determination coefficient (R 2 ), the relative root mean square error (RMSE), the mean absolute error (MAE), variance account for (VAF) and, scaled percent error (SPE) were computed for evaluating the prediction performance of the ANN and MR models developed.…”

Influence of soil properties on amplification of saturated inhomogeneous poroviscoelastic soil profile

“…Several investigations on the presence of plastic or non-plastic fine content in the sandy soil are focused on the soil liquefaction resistance [37,38] and often neglect the impact of this fine content on the amplification of soil response. For this purpose, it is assumed in this study, that the shear modulus depends of the non-cohesive fines content according to the Wichtmann's model [8].…”
