Abstract

In this study, the behaviour of shallow foundations near slopes is studied using nonlinear elastic finite element analysis. Forty-four cases of strip footings resting on cohesionless soils that were studied by Sud (1984)[1] through model tests, have been analyzed. Pressure-settlement relations has been compared with experimental results of (Sud, 1984) [1], and a good agreement between the two has been observed. Ultimate bearing capacity of shallow foundations near slopes was evaluated using the intersection of two tangents of pressure-settlement curve. The values of ultimate bearing capacity agree well also with (Sud, 1984) [1]. A non-dimensional correlation has been developed between the settlement of footing erected near slope (Sβ) and the settlement of footing resting on level ground (So). The relationship (Sβ/So versus De/B) can be expressed by a unique relation for different slope angles (β). This relation has been found to be dependent on distance of the edge of the footing from slope shoulder; De, and angle of slope; β, while it is independent of the relative density of sand; DR, and the factor of safety. By knowing the settlement of a footing resting on a level ground, the settlement of a footing erected near slope can be evaluated using this correlation.
