Abstract | Model testing has proven to be an effective tool in the study of soil-structure systems. While primarily used in research work, this method of evaluation is also applicable to the solution of many types of complex design problems. Because of its workability and relatively simple characteristics, sand is the most applicable soil type. The major difficulty encountered in the development of a model testing apparatus is the preparation of a uniform soil medium. For an effective test apparatus utilizing cohesionless soils, the method of soil placement must be capable of reproducing uniform deposits over a large range of relative densities. The purpose of this study was to investigate a sieving technique of sand placement. The apparatus was evaluated for its ability to produce sand bed uniformity and vary density by varying sieve sizes. A uniform fine sand and two sieve sizes were used in the evaluation. Test results indicate that the device provides an effective method of sand placement at two or possibly three densities over an estimated range of relative densities of 50 to 75 percent. Closer control of sand density does not appear possible due to the critical relationships between sieve size, sand gradation and particle size. |
