Mechanical Response Analysis for an Active–Passive Pile Adjacent to Surcharge Load

نویسندگان

چکیده

Due to the complexity of pile–soil interaction, there is little research on active–passive piles that bear pile-top load transmitted from superstructure and pile shaft caused by lateral soil movement around simultaneously. The purpose this study analyze displacement internal force piles. Most design codes in China use elastic resistance method describe relationship between horizontal pile, but not accurate enough deformation when large. For case, passive adjacent surcharge can be described stages, p–y curve used express pile. Additionally, taking both active (vertical force, bending moment top) into account, deflection differential equation herein established, a corresponding finite difference program implemented obtain calculations pursuant equation. correctness analysis was verified two test cases. results show our calculation effectively judge flow state accurately reflect nonlinear characteristics pile-soil interaction. Moreover, influence depth under condition significantly greater than condition, maximum pile-bending appears near interface soft hard layer.

Harmonic Response of Pile Groups to Dynamic Loading

A completely general method of analysis for three-dimensional raked piles under harmonic excitation is discussed. The piles have been represented by a three-dimensional frame structure and the soil has been represented by a boundary element discretization scheme. A computer program has been written which carries out this analysis and produces a group stiffness matrix that can be included as a f...

Study on Load-Bearing Characteristics of a New Pile Group Foundation for an Offshore Wind Turbine

Because offshore wind turbines are high-rise structures, they transfer large horizontal loads and moments to their foundations. One of the keys to designing a foundation is determining the sensitivities and laws affecting its load-bearing capacity. In this study, this procedure was carried out for a new high-rise cap pile group foundation adapted to the loading characteristics of offshore wind ...
