A Study of Deep Excavations and Excavation Support Systems in Soft Soils

This study investigated deep excavations, its effects on adjacent structures and excavation support systems. This was in the light of concern that the structural integrity of buildings is compromised when Deep Excavations are executed in close proximity to a structure. In densely built-up areas with high land value, the trend is towards building higher and deeper, often adjacent to existing structures. Such projects involve the adoption of tight ground movement criteria. This study investigated challenges posed by Deep Excavations that included; ground deformations, seepage of water in the excavation site and stability of excavation slopes. A number of documented case studies were analysed. Data for this study were obtained by document analysis of existing literature. The findings of this study will be utilized to establish a suitable procedure of conducting deep excavations.
