Abstract: “Inadequate space in urban area has set forth a challenging trend to go deeper into the ground, and increase the space required for providing public amenities, parking space and for housing utilities. Closely spaced structures in the vicinity of excavation, soft and compressible landfills, presence of underground utilities, and restriction of lateral ground movements have made the supporting systems a formidable task to execute [3]. Deep excavations are supported by systems like conventional retaining walls, sheet pile walls, braced walls, diaphragm walls and pile walls. In urban areas noise and vibration creating supporting systems are avoided and hence Pile wall can be used effectively. In this work, numerical modelling of Pile Wall using PLAXIS – 3D is conducted in order to carry out parametric studies, effect of stage wise excavation on ground and pile wall deformation.”
