Numerical modelling of circular plate anchors in sand under partially drained cyclic loading
Numerical modelling of circular plate anchors in sand under partially drained cyclic loading
This study presents a numerical model of a horizontal circular plate anchor in dense sand under partially drained cyclic loading. The model employed the SANISAND-MS constitutive model and coupled stress-pore fluid diffusion analysis to capture the accumulated anchor displacement and excess pore pressure buildup during cyclic loading. The model parameters were calibrated to drained and undrained cyclic triaxial test results, revealing the necessity of two different parameter sets to appropriately capture the responses. The partially drained response of plate anchors was better matched using the drained cyclic parameters, with adjustment required in the MS parameter . The model performance was validated by simulating three centrifuge tests with variations in cyclic mean load and amplitude. Some insights on the predictive capability and the limitations of the model are provided in this paper.
