Abstract:
This paper presents a parametric study for the pile response and ground movements due to deep excavations supported
by stable retaining walls. The coupled behaviour of a single pile subjected to excavation induced ground movements is
analysed using the finite element method, which has the ability to simulate construction sequences and various lateral
earth retaining systems. The constitutive behaviour of the soil is modelled using the Mohr-Coulomb model. The pile is
assumed to have the linear elastic behaviour. The numerical model was verified using centrifuge test data found in the
literature and a parametric study is carried out to develop design charts to establish variation patterns among number of
influence factors such as geometry of the excavation, soil properties, structural system variables, pile fixity conditions
and pile location with respect to the excavation.
