View License Agreement This paper examines 6 stone column projects constructed throughout the United States from 1985 to 1988 in which quick vertical load tests were performed to predict performance of foundations and to compare this prediction with the design prediction. The stone columns were constructed through various types of soil including sand, clay, silt, peat and construction debris. The configuration of the load tests varied from .76 m (30 inch) diameter to 1.8 m (6 foot) square steel plates with loads from 89 kN to 916 kN (10 to 103 tons) on one to four stone columns. The proposed construction, design load, settlement criteria and soil profile are reviewed for each project. Special emphasis is placed on using the load test data to predict the settlement of the planned foundations. In addition, the configuration and mechanics of the load test set ups are presented. | ||
