dc.description.abstract | In this paper, three contents are ineluded. (1) Model experiment on water pressure propaga-tion in sandy aquifer, (2) Influence of the change of effective stress on water pressure propagationin sandy aquifer, (3) Estimate of settlement in sandy aquifer due to repetitious variation of waterpressure.From the model experiment in which water pressure periodically varied was applied to sandyaquifer, it may he clear that the coefficient Cν in Eq. (1) can be estimate from the damping ofwater pressure with distance and the velocity of its propagation. On the other hand, the coefficientCν is affected by effective pressure in sandy aquifer. The equation which expresses relation be-tween Cν and effective pressure, can be shown using the laboratory tests results on the compressi-bility and permeability of sand.Finally, residual settlement εR in sandy aquifer due to repetitious variation of effective pres-sure follows the equation, where N is repetitious number, α and β are constants. | en |
