Advanced Soil Constitutive Models in Practical Applications with a Focus on Cyclic Loadings

Engineering firms specializing in geotechnics often face complex challenges, even though standard soil models are typically used for calculations. However, in more complex situations, such as cyclic loading or soft soils, these models have significant limitations. This study seeks to apply advanced constitutive soil models to practical projects. Improvements in the hypoplastic model demonstrate that enhancing the monotonic behavior of granular soils can also improve their cyclic and seismic responses. Results from three advanced models indicate that an improvement of hypoplastic model more accurately captures soil-pile interaction during seismic events, particularly in predicting variations in acceleration and pore water pressure.
