The Bearing Capacity Analysis Of Pile Foundation Of Jacket Platform Under Inclined Load

Complex marine environment makes the geological exploration of offshore platform construction more difficult to obtain comprehensive and accurate geological data, therefore, it is very necessary to do some analysis and research on the offshore platform pile-soil characteristics of the system bearing capacity.The researches on the Bearing capacity of piles have gone through a long period of time, and the related theories have also been improved continuously. However, the studies are relatively less for the piles under inclined load (to bear both vertical and horizontal load).First, in this article the analysis is provided which use the finite element software ABAQUS to simulate the three-dimensional nonlinear analysis of pile-soil interaction. Then the main performances of piles under inclined load are researched, such as the pile side friction distribution, the pile axial force distribution, the pile bending moment, the pile-soil deformation, and the load-displacement curve, and it shows that in the homogeneous layered soil, the simulation results using finite element method are consistent with the research results using the existing theories.In view of the finite element analysis of the foundation, the capacity envelope on the vertical-horizontal load bearing capacity is analyzed, and the envelope is fitted by the elliptic equations. At the same time, the formula presented in this thesis is compared and discussed with traditional experience formula, and some modifications are made based on the traditional experience formula.
