Abstract

A review of design procedures for slope stabilization by stone columns is given. Stone column design and construction is reviewed for three projects where natural slopes were stabilized by stone columns. Stone column construction was achieved by the wet vibro-replacement method, a dry preaugering technique, and the dry, bottom-feed method. Instrumentation is described and performance of the stone columns on these projects is reviewed. Slope movement has stopped completely in all cases.
