摘      要：This study examines the use of granular soils mixed with tire derived aggregates(TDA)as an underlying soil layer for surface *** benefit of this geotechnical seismic isolation(GSI)scheme is threefold:the seismic force and displacement are significantly reduced;the construction is similar to that of a regular compacted granular fill and the re-use of scrap tires has an assertive environmental *** features highlight the rubber/soil mixtures(RSM)as a promising seismic isolation technique for infrastructure and large-scale *** seismic isolation capabilities of a rubber-soil foundation layer are investigated,using well defined material properties,and the direct analysis method of the soil-structure system,in the form of a simple oscillator on a soil *** influence of the RSM layer on the fundamental variables of the seismic response,namely the base shear and the total drift displacement of the structure on deformable soil,is *** structure′s overall stability is studied by means of monotonic lateral load analysis and incremental dynamic analysis,varying the slenderness of the structure and the synthesis of the *** effectiveness and capabilities of the RSM isolation scheme are presented and discussed.
