- Effect of limiting soil pressure on pile group adjacent to a failed excavation
- Ong, D. E. L.; Leung, C. F.; Chow, Y. K.
- Deep excavation may result in lateral soil movement that may threaten the structural integrity of nearby existing pile foundations. In this paper, a pile group consisting of 4 nos. of 900-mm diameter bored piles was instrumented to provide an in-sight into the study of pile-soil interaction. By chance, the instrumented pile group failed by displacing laterally due to excessive soil movement resulted from a nearby slope excavation. Benchmarking between field data and back-analysis nsing Finite Element Metbod (FEM) as well as an established numerical method were carried out to understand the pile group behaviour when subjected to large-strain lateral soil movement or soil flow. The disadvantage of modelling a 3-D pile group in 2-D environment is also addressed.
