Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

An elasto-plastic model to describe the undrained cyclic behavior of saturated sand with initial static shear

With the aim of simulating the behavior of saturated sand with initial static shear (i.e., sloped ground) undergoing undrained cyclic loading, which leads to liquefaction and large cyclic shear strain development, an elastoplastic constitutive model which can describe both monotonic and cyclic torsional shear behaviors of saturated sand under drained and/or undrained conditions is presented. It...

The undrained shear strength characteristics of silty sand : an experimental study of the eff ect of fi nes

This laboratory investigation has been conducted to elucidate how the fi nes fraction affects the undrained residual shear strength and liquefaction potential of sand-silt mixtures (Algeria). A series of monotonic and cyclic undrained triaxial tests were carried out on undrained, reconstituted, saturated samples of sand with varying fi nes content ranging from 0 to 50%. These were undertaken in...

Simulation of Stress-Strain Behavior of Saturated Sand in Undrained Triaxial Tests Based on Genetic Adaptive Neural Networks

This study applies artificial neural networks (ANN) to simulate the soil stress-strain relationship observed in test data from triaxial shear testing of saturated sand. A genetic algorithm is used to obtain an optimal framework for the ANN. The results show that the proposed genetic adaptive neural network (GANN) can effectively model undrained monotonic and cyclic triaxial behaviour of saturat...
