EXPERIMENTS ON DYNAMIC PROPERTIES OF FGC TREATED SOILS AND MODEL TREATED GROUND
|
´˜^i‰pjF
The dynamic properties of FGC treated soils (Fly-ash. Gypsum and Cement Deep-Mixing Method) are experimentally studied and shaking table tests of model treated ground are performed. On the basis of these experiments, the properties needed for earthquake response analyses are estimated. The dynamic properties of FGC treated soils are affected by cyclic load step confining pressure, and especially shear strain level. These properties change in a wide range by controlling the mixing ratio of FGC. It suggests a possibility to produce appropriate dynamic properties of FGC treated soils. The response of the model treated ground also changes according to the mixing ratio.
