Abstract

Abstract

During the service of engineering structures such as high-rise buildings， viaducts， and marine platforms， pile foundations typically bear complex jmlateral and vertical loads. Existing research often overlooks the impact of the coupling effect of multi-directional loads on the lateral deformation of pile foundations. This study considered a single pile as a finite-length Euler-Bernoulli beam and proposed an analytical solution for its mechanical response under the influence of coupled multi-directional loads， which had been validated through ABAQUS finite element simulations. The results showed that the influence of vertical loads on lateral displacement and bending moments increased with the increase of horizontal loads. An increase in both horizontal and vertical loads resulted to greater lateral displacement and bending moments， with the impact of horizontal loads being more significant. A coupling effect was observed between bending moments and vertical loads， and its influence increased with higher bending moments.An increase in the soil’s elastic modulus reduced the displacement of the pile foundation， with a greater impact on the internal forces than on the lateral displacement.
