The purpose of this study was to document construction procedures, monitor field performance, and make recommendations as to the effectiveness and future use of the stone column procedure for foundation stabilization. This effort was executed by use of field inspections, photologs, instrumentation to monitor foundation and field response, 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 observed to be approximately 9 inches as compared to the 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 judged to be satisfactory in that embankment stability was obtained.
