【Abstract】 Using the three-dimensional dynamics FE-FD coupling method and the constitutive model of elastoplastic saturated soil,the nonlinear numerical simulation is operated on the shake-talbe experiments against system of liquefid soil-piles,during which the laws of pore water pressure in flowing and the influence between flow distortion and internal force,lateral displacement in piles back and forth are discussed.更多还原
