Cone Model for Two Surface Foundations on Layered Soil

The cone model is applied to vibration analysis of 2 foundations on a layered soil half space. In the analysis, the total stress field in the subsoil is divided into the free-field and the scattering field. Seed's simplified method is adopted for the free-field analysis, while the cone model is proposed for analyzing the dynamic scattering stress wave field. The shear stress field and compressive stress field in the layered stratum with 2 scattering sources are calculated by shear cone and compressive cone, respectively. Furthermore, the stress fields in the subsoil with 2 foundations are divided into 6 zones, and the P wave and S wave are analyzed in each zone. Numerical results are provided to illustrate features of the added stress field for 2 surface foundations under vertical and horizontal sinusoidal force excitation. The proposed cone model may be useful in handling some of the complex problems associated with multiscattering sources.
