| Abstract | The paper deals with the dynamic behavior of offshore piles embedded in soft clay, and estimating the critical embedded pile length. ABAQUS is a finite element program, which was used to simulate the problem. The soil was modeled in two case elastic state model and elastoplastic state model represented by cam-clay model, three dimension element used to represent the interaction between pile and soil, laboratory tests are used to obtain the real properties of soil and to descried interface. Test results are used to modify the elastic equation used by Matlock and Reese to calculate critical embedded pile length for pile embedded in elastoplastic soil. Also, tests show that the critical embedded pile length is increased about (20 % to 40 %) when changing the soil model from elastic to elastoplastic, as piles embedded in elastoplastic soil depend on soil strength, interface properties and pile rigidity. The pile head displacement is increased about 90 % while the bending moment is deceased by 10 % at pile head. |
