| Lateral loading tests were conducted on model piles to investigate the nonlinear interaction between soil and piles. A 3D FEM analysis is then carried out to simulate the test results, where the 2nd invariant of stress and strain deviators are introduced to consider the 3D nonlinearity of soil. It is shown that the 3D FEM analysis has good potential to accurately simulate the test results such as lateral load-displacement relationships, bending moment, shear force and subgrade reaction force along the piles. Characteristic features of the subgrade reaction coefficient - displacement relationships at each soil depth are discussed through a comparison with conventional modeling method. |
