TL;DR: In this article, a mathematical model for a combined soil subgrade plus structural elements in contact with the subgrade (e.g., a mat foundation) is presented, which can be visualized as a spring-supported beam column under constant axial tension.
Abstract: A mathematical model for a combined soil subgrade plus structurallement in contact with the subgrade (e.g., a mat foundation) is presented. The structural portion of the model is a conventional flexural element. The subgrade portion of the model is Pasternak's hypothesis, which is fundamentally more accurate than the commonly used Winkler hypothesis. The novel element developed in this note is not the individual model components, but the fact that the combined model can be visualized as a spring‐supported beam‐column under constant axial tension. The column tension and springs represent the subgrade effects. This beam‐column analogy is useful in practice because it allows more accurate modeling of soil‐structure interaction within the capabilities of existing structural analysis computer software.

TL;DR: In this paper, an analytical investigation of the seasonally frozen soil effects on the seismic behavior of a soil-pile-bridge pier system was presented, where Elastic-plastic finite element (FE) analyses were conducted to obtain the cyclic behavior of the soilpile system under the unfrozen and frozen soil condition.

TL;DR: Sixty-three static pile load tests were analyzed with respect to published soil properties to validate or refine well-known pile design methods as discussed by the authors, and some comments were made concerning pile design in general.
Abstract: Sixty-three static pile load tests were analyzed with respect to published soil properties to validate or refine well-known pile design methods. Even though most of the data used to carry out this study are for driven piles, some consideration was given to bored piles. Some comments were made concerning pile design in general. Resume : Soixante trois essais de chargement statique de pieux ont ete analyses en fonction des proprietes des sols qui ont ete publiees afin de valider ou de raffiner des methodes de conception de pieux bien connues. Meme si la plupart des donnees utilisees pour realiser la presente etude correspondent a des pieux battus, les pieux fores ont aussi ete consideres. Des commentaires ont aussi ete donnes pour la conception des pieux en general. Mots cles : capacite portante, resistance en frottement, resistance en pointe, conception des pieux, essai de chargement sur pieux.

TL;DR: This paper describes prediction of the residual strength of soil based on index properties using two machine learning techniques and finds the SVM model to be better than the developed ANN models.
Abstract: Stability with first time or reactivated landslides depends upon the residual shear strength of soil. This paper describes prediction of the residual strength of soil based on index properties using two machine learning techniques. Different Artificial Neural Network (ANN) models and Support Vector Machine (SVM) techniques have been used. SVM aims at minimizing a bound on the generalization error of a model rather than at minimizing the error on the training data only. The ANN models along with their generalizations capabilities are presented here for comparisons. This study also highlights the capability of SVM model over ANN models for the prediction of the residual strength of soil. Based on different statistical parameters, the SVM model is found to be better than the developed ANN models. A model equation has been developed for prediction of the residual strength based on the SVM for practicing geotechnical engineers. Sensitivity analyses have been also performed to investigate the effects of different index properties on the residual strength of soil.
