Stone columns offer one potential technique for rehabilitating the foundations beneath existing structures to withstand both static and earthquake loadings. A detailed discussion of stone columns has been given in a previously published Federal Highway Administration FHWA report entitled Design and Construction of Stone Column, Vol I. The present report supplements the FHWA report, presenting earthquake engineering and excess pore pressure considerations and giving the previously unpublished appendixes. Seed and Bookers method is presented for estimating the dissipation of excess pore pressure in stone column improved ground during strong motion earthquakes. Keywords Bearing capacity, Earthquake loading, In-situ deep compaction, Liquefaction, Pore water pressure, Remedial treatments, Settlement, Soil reinforcement, Soils, Stability, Stone columns.
