Abstract: This paper presents a case study of a deep excavation design in a building in Chengdu. The application of the beam on elastic foundation method in the deep excavation design as well as the internal force estimation is introduced. The stability of the excavation is evaluated by using Bishop Method. Various methods are used to estimate the excavation induced ground settlement. Both advantages and disadvantage aspects of the beam on elastic foundation method in the deep excavation design are also discussed.

Key words: Deep Excavation Supports, Beam on Elastic Foundations, Slope Stability.
