Abstract
The problem of sandy soils as to how they behave when they contain air or gas has been recently addressed in relation to evaluation of cyclic resistance during earthquakes. In order to shed some light on this issue, some laboratory tests were conducted on sand samples prepared in the triaxial test apparatus. The outcome of the tests disclosed that the degree of imperfect saturation can be quantified by way of the propagation velocity Vp of compressional wave or P-wave and that the cyclic resistance exhibits significant increase if the velocity Vp drops below 700 m/sec, a value smaller than the propagation velocity through water.
