| Research Abstract |
In liquefaction countermeasure of the ground and underground storage of the gas or deep underground area development, after the saturated ground is once unsaturated, though the evaluation by the process which returns to the saturation state again is required, it is present state that these phenomena are not always clarified. Then, in this study, element laboratory test was mainly carried out in order to research the mechanism in saturation ratio rise process in the ground under positive pressure, and it verified the unsaturated model in the conversion to the saturation process.
