Dynamic Behavior of Ground Improved Using a Crushed

2019-5-15  The improvement of soft clay and dredged soils to carry structures is increasingly important. In this study, the dynamic behavior of a crushed stone foundation wall in clay soil was analyzed using a 1g shaking table test. The response accelerations and spectra for three input ground motions were analyzed relative to the distance from the foundation wall, confirming that the acceleration was ...

stone columns – determination of the soil improvement

2011-10-10  A stone column is one of the soil stabilizing methods that is used to increase strength, decrease the compressibility of soft and loose fine graded soils, accelerate a consolidation effect and reduce the liquefaction potential of soils. The columns consist of compacted gravel or crushed stone arranged by avibrator.

Ground Improvement Technique – A View of Stone

2018-12-15  The area treated by stone columns can be used to support only flexible structures such as embankment, oil storage tank, etc. because, the settlement even after treatment with stone column can be large (50-200 mm). Without stone columns the settlement could have been 3-4 times higher and also the bearing capacity would have been much less.
