(DOC) Behavior of Single Pile Subjected to Lateral Soil

When an excavation was carried out near an existing pile foundation, lateral soil movement would be induced and in turn generate pile responses (passive pile phenomenon). Previous studies on this phenomenon utilized free-field techniques where the

(PDF) INFLUENCE OF PILE SUPPORTING EXCAVATION PROPERTIES

As excavation proceeds, the surrounding soils will move toward the excavation and their movement will induce bending moments and deflections in the existing pile groups. The existing pile response due to the excavation-induced lateral soil movements had been studied previously by using numerical analysis and laboratory analysis, but there are

The Responses of an End-Bearing Pile to Adjacent

that lateral restraints imposed on the pile head have a significant influence on induced pile bending moment. Induced bending moment due to excavation can exceed the pile bending capacity. Poulos and Chen [25] developed design charts to compute the lateral behaviour of a single pile adjacent to deep excavation in soft ground.

[PDF] Pile-Soil Interaction and Settlement Effects Induced

Aug 01, 2016 · AbstractDeep excavations may cause settlement and damage to adjacent buildings, even if they are found on piles. The corresponding pile deformations are determined by axial and lateral effects. This paper describes an analytical model relating axial pile deformation to the vertical soil displacement resulting from the deep excavation and also suggests ways to …

A Prediction Method Based on Elasticity and Soil-Structure

Jan 15, 2021 · Abstract. Deep-excavations cause ground movements and, consequently, the deformations of the pile foundation of adjacent buildings. For deep foundations, the soil-pile-structure problem is influenced by both the greenfield soil movement due to excavation and the complex pile-soil, pile-soil-pile and pile-structure interactions.
