An analytical method to predict the immediate settlement of a sand base footing is discussed in this paper. The summary of the results is shown below. Secant modulus of elasticity has been derived from the relations between stress and strain obtained from triaxial compression tests. This modulus is the expansion of Janbu's experimental equation and varies according to the change of lateral pressure and strain. The value of stress used in calculating the settlement is derived from stresses in ground which have been calculated on the assumption that the base is elastic. The result of calculation is as follows. The settlement of a circular footing goes to 3D (D : the diameter of the footing) but most of settlements are within D. The settlement of a foundation continuous footing goes to 5 B (B : the width of the footing) but most of the settlements are within 1.5 B.
