“…Several studies have been dedicated to the investigation of the effect of different physical parameters on the void ratio parameter for various types of mineral waste. In this regard, there have been many studies that investigated the effect of the effective stress parameter on the void ratio parameter in mineral tailings [1][2][3][4][5][6][7]. e results indicated that increasing the effective stress leads to nonlinear reduction of the void ratio for various types of tailings.…”

Mineral tailing deposits are one of the most important issues in the field of geotechnical engineering. The void ratio of mineral tailings is an essential parameter for investigating the geotechnical behavior of tailings. However, there has not yet been a comprehensive empirical formulation for initial prediction of the void ratio of mineral tailings. In this study, the void ratio of various types of mineral waste is estimated by using gene expression programming (GEP). Therefore, taking into consideration the effective physical parameters that affect the estimation of this parameter, eight different models are presented. A reliable experimental database collected from different sources in the literature was applied to develop the GEP models. The performance of the developed GEP models was measured based on coefficient of determination (R2), mean absolute error (MAE), and root mean square error (RMSE). According to the results, the model with effective stress σ ′ , initial void ratio (e0), and parameters of R2 = 0.92, MAE = 0.109, and RMSE = 0.180 performed the best. Finally, a new empirical formulation for the initial prediction of the void ratio parameter is proposed based on the aforementioned analyses.

Reexamination of effect of plasticity on liquefaction resistance of low-plasticity fine-grained soils and its potential application

The paper summarizes a compilation of existing cyclic experimental data on reconstituted and undisturbed specimens of low-plasticity fine-grained soils to assess liquefaction resistance. The authors normalized the data to reduce the effect of other relevant factors such as shear mode, density, effective confining stress and cyclic loading frequency. It is indicated that liquefaction resistance of the specimens reconstituted using slurry consolidation approach is lower than that of the undisturbed specimens. The liquefaction resistance for undisturbed specimens decreases with an increase in the plasticity index up to 4-5 and then increases with a further increase in plasticity index. A new correction factor K PI to estimate the effect of plasticity index on cyclic resistance ratio is proposed for design purposes and added into the framework of liquefaction evaluation of claylike fine-grained soils with PI of 7-18 (change to 5-18, if ML-CL) on the base of the approach of Boulanger and Idriss. Because the effect of plasticity index on liquefaction resistance is slight when the plasticity index is \7, it is suggested that the liquefaction evaluation of sandlike fine-grained soils with PI of 0-7 (changed to 0-5, if ML-CL) follows the framework of simplified procedures using SPT and CPT data.
