A new technique is proposed to calculate final settlement for non-isotropic

nonlinear elastic subsoils by using the data of in-situ tests. Firstly

hyperbolic curves are fitted out from the data of load tests or screw plate tests on stratified

undisturbed soils. Secondly

the relationships between additional stresses and tangent modulus of the soils are established; and additional stress factor is added to consider the influences of foundation depth

non-isotropic and nonlinear elastic character. Finally

the total final settlement is calculated by using hyperbolic curve tangent modulus equation and additional stresses. After fitting hyperbolic curves from the data of load tests

different equations of hyperbolic curve tangent modulus for soils are obtained to find the settlements under different loads. The calculated results show that

the predicted settlements are well in agreement with those from load tests. This technique may be potential to calculate settlements with its simple principle

reliable parameters and accurate results.
