振動時の間げき水圧に関する基礎的研究

Abstract

In this paper, the properties of pore water pressure in saturated sand deposits subjectedto continuous vibratory force are investigated theoretically and experimentally.First, the situation when liquefaction occurs, in particular the process of dissipationafter liquefaction is considered and analyzed under the assumption that the sand depositssettle down only vertically by the action of the vibratory force. On the basis of thatresult, the factores which affect the value of pore water pressure and profile of distributionof it are examind.Then, several results of vibratory experiment using a rectangular sand container arediscussed and compared with the theoretical values.
