In this laboratory test, saturated loose sands were shaken causing their liquefaction, and the settlement of sands and excess pore water pressure were measured. Sands showed delicate response for vibration and it was observed that slight difference in the qualities of the sands affected the result of the test. This test result proved that the liquefaction is caused by the destruction of the skeleton due to vibration, and the sand grains become suspended, there by causing the rise of the excess pore water pressure, equal to the submerged weight of sand. At the same time, this liquefaction starts the sinking of grains. (consolidation) This type of consolidation process of sands showed, it was entirely different from that of the heat-conducting type of clay.
