【Abstract】 In the paper, the pore water pressure generation model of loess was first applied to the finite element numerical analysis of earthquake liquefaction in loess improved by gravel piles. The calculation results show that the pore water pressure in a saturated loess increased very rapidly during earthquake and dissipated slowly after earthquake and that the large settlement was induced. The anti liquefaction(draining water) effect of gravel piles is obvious, but the tributary area to gravel pile is limited.更多还原
