The pile also transfers load from its tip directly to the underlying soil. While the interaction of these two load transfer mechanisms is complex, in the static analysis of friction piles, both are considered to act at the

3D numerical analysis of pile response due to soil

Jul 05, 2021 · The parametric study showed that the pile responses are strongly influenced by the excavation depth, relative pile location, sand density, excavation support system and pile length. It also showed that the response of a pile within a group depends on its location in relation to the other piles of the pile group, its distance from the retaining

Behavior of cantilever secant pile wall supporting

In the course of underground Mass Rapid Transit construction in Singapore, there was a cut and cover excavation that ran parallel to an existing expressway viaduct supported by piles. Engineers are concerned on the effects of excavation-induced soil movement on the adjacent existing pile foundations supporting the viaduct structure and had set stringent deflection limit for the pile …

Pile-Soil Interaction and Settlement Effects Induced by

For end-bearing piles, p s is expected to be significant only if the pile bases are very close to the excavation, as shown similarly for tunnels by Kaalberg et al. and Lee and Ng ().Stress relief around the pile base can lead to additional mobilization of positive shaft friction. The settlement under the pile base, p b, may be calculated without interaction with the piles, for example, with …
