Analysis of Ground and Building Response Around Deep Excavations in Sand

Ground-structure interaction around deep excavations is investigated by superposing different types of structures in the zone of influence of excavation, in 2D and three-dimensional (3D) models. Ground movements modified by the structures are sensitive to the assumptions regarding one of the state variables of the constitutive model, the intergranular strain. The ensuing structure response is described in terms of deformed shape of structure, deflection parameters, and moments induced in the components of the structure. Effects of various parameters, such as live load, number of stories, and distance from excavation, on the response of structure are investigated. The correspondence of the 3D model with the base 2D model is established by comparing the results of free field analyses obtained from these two models. The relationship between equivalent soil modulus in 2D and 3D models is investigated.
