Assessment of 3D Excavation and Adjacent Building's Reponses with Consideration of Excavation-Structure Interaction
This paper investigates the 3D excavation-induced ground and building's settlements by means of 3D numerical simulations. The effects of the excavation responses are studied with and without considering the nearby building. This paper proposes a simplified simulation technique (capturing the plastic behavior of the structure to enhance the realistic modeling of the structure) in which the excavation model and the structure model are decoupled and considered by two separate numerical programs. An iteration scheme is developed to bridge the two models. The results show that the proposed analytical scheme is feasible and the convergence can be reached within several iterations. It allows more in-depth investigation on the structure response such as where the plastic hinge or high potential of damage may occur in the structure. This study also provides valuable insights not only on the interaction characteristics of the soil and the structure adjacent to an excavation site, but also on the effect on the excavation behavior due to inelastic behavior of the adjacent structure.
