Effect of Excavation on the Response of Circular Footing in Sandy Soil
Abstract This paper presents the results of numerical studies carried out to investigate the effect of excavation on the adjacent circular footing. To obtain the response of the circular footing, series of numerical analyses were performed on the footing by incorporating varying parameters such as the footing location from an excavation, varying density of soil and depth of excavations. In the numerical analysis, the footing and sheet pile walls were idealized as a linear elastic materials and nonlinear behaviour of soils using a Mohr–Coulomb model. The paper mainly discusses on the effect of excavations to an adjacent circular footing embedded in medium and dense sandy soil. It is observed from the results that the settlement and bending moment of the footing increases with increase in depth of an excavation. The location at which the effect of excavation on the footing is less significant as termed a safe location or critical location of the footing from excavations. The critical location of the footing based on settlement criteria is 1.5 m from an excavation faces in case of the footing in medium sand and 0.5 m in dense sand.
