Abstract
An existing continuum-based model for a laterally loaded pile embedded in layered soil is developed for long piles in which the vertical deformation of soil is neglected. However, the model is unsuitable for short piles, such as large-diameter caissons and suction buckets, because the soil will have considerable vertical deflections. Thus, this study attempts to modify the existing continuum-based model for laterally loaded long piles, and the aim is to render the model applicable for short piles with large diameters. Two resisting moments are added to the model: A moment on the base of the pile and a moment due to the vertical shear stress of the soil surrounding the pile. The modified continuum-based model is examined in terms of settlement influence factors and validated with the model with finite element (FE) analysis. Our linear static analysis found that the proposed modified continuum-based model is in good agreement with the FE method for short and long piles.
