Abstract

The purpose of this study was to document construction procedures, monitor field performance, and make recommendations concerning the effectiveness and future use of a foundation improvement procedure using stone columns for stabilization. This effort was executed by use of field inspections and photographs, instrumentation to monitor foundation and field responses and laboratory analyses of existing and possible conditions.

Instrumentation included earth pressure meters, a multipoint settlement gage, a horizontal slope inclinometer, a settlement platform and vertical slope inclinometers. Settlement of the foundation after column construction was found to be approximately 8 inches as compared to a predicted total settlement of 16 inches. Initial pressure distribution was affected by the stone columns but long term distribution indicated no relationship to the stone columns. Performance of the stone columns was found to be satisfactory in that an adequate embankment factor of safety was obtained.
