Abstract

Deep excavations are frequently carried out near structural foundations in densely populated metropolitan areas. Those foundations surrounding the excavation site can impose additional lateral pressure on the retaining wall along with backfill pressure. A three-dimensional finite element analysis has been performed in the present study to determine the effect of square and circular footings of the same plan area on the sheet pile wall behaviour. A parametric study is performed by varying the plan area of footing, embedded depth of sheet pile, magnitude of surcharge loads, position of footing above and below the backfill surface from the top edge of the wall, the depth of the loose soil layer, and dredge line slope angle to find out the wall deflection, bending moment, and backfill ground settlement. The results show that the effect of square and circular footing highly influences the wall and backfill soil. However, the effect of square footing on the wall and backfill soil is more substantial than that of circular footing for the same plan area.
