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...

Evaluating the response of new pore pressure transducers for use in dynamic centrifuge tests

Over the past 30 years, the PDCR-81 pore pressure transducer has become a standard instrument for measuring pore pressures in centrifuge experiments. Following the retirement of this transducer and its reduced reliability, it has become vital to find an alternative sensor for use by the geotechnical modelling community. In this paper, the response of the 2Mie pressure transducer is compared aga...

An Energy Based Excess Pore Pressure Generation Model Using Damage Potential

In this paper, application of energy-based excess pore pressure generation model proposed by Park et al. (2008) to develop an improved model for the analysis of liquefaction potential and to predict excess pore pressure (EPP) is examined through experimental and analytical investigations. For more realistic description of the dynamic responses of saturated sand undrained dynamic triaxial tests ...
