Abstract
Sand compaction piles which are constructed as compacted sand piles in the weak soils are used frequently in Korea as one of the soil improvement techniques. But it is necessary to find a new technique which can replace sand compaction piles because of decrease of sand resources and increase of sand cost. In this study, load tests of model composite ground which is composed ofgravel compaction piles and clays are executed in order to find out bearing capacity characteristics and the same load tests of sand compaction piles are executed to compare the results of both load tests. Area replacement ratios of gravel compaction piles and those of sand compaction piles are 30%, 40%, and 50%, respectively and a model composite ground is preconsolidated by centrifugal consolidation apparatus before the load test. And the bearing capacities from test results are compared with those predicted by existing formulas.
