Analytical solution of seismic displacement of foundations next to slope by cone model

ABSTRACT

An important challenge in dynamic soil–structure interaction analysis is the soil profile modelling. The cone model can model the soil and foundation in SSI problems. The cone model works well in low and intermediate frequency ranges such as machine vibrations and earthquakes. In the present study, the dynamic behaviour of a rigid disk next to slope will be determined by cone model. Cone frustums are used to determine how waves propagate below the foundation. The proposed method is able to determine the dynamic behaviour of a disk in various distances next to slope. The soil is assumed as one layer. The presented model is a new analytical model which is capable to estimate the foundations stiffness next to slope in a simple way. Results of the proposed method are verified with experimental and analytical results of other researchers which is in good agreement.
