GROUND MODIFICATION SYSTEMS (STONE COLUMNS AND WICK DRAINS IN JEFFERSON COUNTY)

The purpose of this study was to document construction procedures, monitor field performance, and make recommendations as to the effectiveness and future use of stone column and wick drains for ground modification purposes. This project involved the use of wick drains to accelerate consolidation in bridge approach foundations and stone columns to improve foundation support for reinforced soil walls supporting bridge abutments. This effort was executed by use of field inspections, photologs, and instrumentation to monitor field response. Instrumentation included earth pressuremeters, multipoint settlement gages, slope inclinometers, settlement platforms, and piezometers. Wick drain performance was satisfactory. One reinforced soil wall failed and the other was marginally stable. The failure appears to be the result of a combination of a weak foundation layer that was disturbed by stone column construction, high foundation pore pressure, and rapid wall construction.
