Abstract EN
In geotechnical mediums where the bearing capacity of upper layers of soil is not suitable for use of the shallow foundations, piles are usually used as deep foundations to transfer loads to the stronger lower layers.
Here, the seismic behavior of single pile and pile group constructed in saturated soft kaolin clay under three different earthquakes using Abacus 3D software is investigated.
The aluminum material considering the linear elastic model has been used for the piles, and the nonlinear kinematic hardening model with Von Mises failure criterion has been considered for clay.
This model can consider the soil stiffness degradation by increasing the number of cyclic loading.
Three different methods have been used to calibrate the model parameters, two of them are new methods.
In all calibration methods, the cyclic shear and undrained cyclic triaxial tests are used.
The results obtained from the numerical analysis of the soil-pile model are in relatively good agreement with the centrifuge model results.
According to the results, the variation of earthquake frequency and intensity affects the bending moment created along the pile and also the distance between piles in a pile group affects the amount of the interaction between them.
