heal.abstract	This paper studies how 2D numerical analyses may be accurately used for simulating the truly 3D problem of the seismic response of improved sites. Specifically, parametric results are compared from pertinent 3D and 2D seismic ground response analyses and a methodology is proposed for replacing the time-consuming (and usually unavailable) 3D analyses with ""equivalent"" 2D analyses that closely simulate the results of the 3D analyses. Emphasis is put on replacement and solidification methods of soft (cohesive) soils and on three (3) improvement geometries: (a) an embedded soldier pile wall, (b) a grid of columns/piles and (c) a grid of closed square cells. © 2006 Taylor & Francis Group.	en
