Elastic-Plastic Solutions for Laterally Loaded Piles in Layered Soils
Publication: Journal of Engineering Mechanics
Volume 139, Issue 11
Abstract
In geotechnical practice, it is important to quantify the response of laterally loaded piles in layered soil systems. In this paper, semianalytical solutions were developed to assess the static behavior of vertical piles embedded in multiple-layered soil systems and subjected to lateral loads. The behavior of the surrounding soil was idealized as an elastic-perfectly plastic model. The basic idea of the subgrade reaction theory was used to obtain the governing differential equations in terms of pile lateral deflection. Combining with continuity conditions at the adjacent pile segments, the response of the whole pile was expressed through the deflections and lateral forces at the pile head in a matrix form. The validation of the proposed solutions was verified by other theoretical solutions and measured data. The layering effect of subgrade soils on the response of the laterally loaded pile was also discussed.
