A simplified elastic analysis of tunnel-piled structure

Jan 01, 2017 · In urban areas, engineers often need to assess tunnelling-induced displacements of piled structures and the resulting potential for damage. This paper presents an elastic study of tunnel-pile-structure interaction through Winkler-based Two-Stage Analysis Methods (TSAMs), focusing on structural displacements resulting from tunnel excavation beneath piled frames or …

(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

The Effects of Multipropped Deep Excavation-Induced Ground

Oct 24, 2020 · This was because of degradation of sand stiffness due to excavation-induced stress and the plastic strain generated surrounding the piles due to excavation-induced stress release. Since the initial excavation stages (0 < h/H e < 0.68) are adjacent to the pile shaft, the shafts of the piles were affected by excavation-induced plastic strain.

Pile Behavior due to Excavation-Induced Soil Movement in

Jan 01, 2006 · For a pile located at 1 m behind the wall where the soil experiences large shear strain (> 2 %) due to stress relief resulting from the excavation, the calculated pile response is in good agreement with the measured data if the correct soil shear strength obtained from postexcavation is used in the analysis. However, if the original soil shear
