... of insufficient bearing capacity of pile foundations on in-service wellhead platforms is becoming increasingly prominent. The old platforms cannot be expanded and renovated on a large scale, and the oilfield production capacity cannot be effectively released. At the same time, marginal oil fields in the Bohai Sea...

... nonlinear time-history analyses to compare major design parameters like horizontal stresses and deformations of the pile foundation and upper platform structure. Results indicate a significant increase in pile deformation and stress after accounting for soil strength reduction, highlighting the importance...

... ABSTRACT Traditional foundation structure for unmanned vehicle typically adopts conventional plate-stiffener structures, and the low-frequency vibration reduction effect is not ideal, and the space for further optimization is limited, so it is an urgent need to apply novel design concepts...

INTRODUCTION In piled foundations, pile displacements mobilise soil reactions (subgrade reactions), that in turn induce...

... ABSTRACT The increase in rotor size and wind farm water depth has led to more severe environmental load conditions for offshore wind turbines, challenging the design of the foundations to resist the combined loads. To improve the lateral performance of traditional foundations, various hybrid...
