Application of the Strain Wedge Model in Soil-pile Interaction Analysis of Pile-stabilized Slopes

摘要

This paper presents a new method for analyzing pile-stabilized slopes using the Strain Wedge Model (SWM) technique. The developed method allows for the assessment of mobilized and ultimate soil pressure and its distribution along the pile segment above the slip surface based on soil-pile interaction. The proposed technique accounts for the influence of soil and pile properties as well as pile spacing on the interaction between the piles and surrounding soils. The presented method, as well as Finite Element (FE) analysis, is used to derive greater insight into the effect of pile row interaction on the mobilized and ultimate force exerted on the stabilizing piles and the corresponding pile deflection.
