The invention discloses a liquefiable sandy soil structure. The liquefiable sandy soil structure comprises a liquefiable sandy soil layer. The lower surface of the liquefiable sandy soil layer is provided with a concrete gravel layer. The thickness of the concrete gravel layer is smaller than that of the liquefiable sandy soil layer. Non-woven cloth is laid between the liquefiable sandy soil layer and the concrete gravel layer. The lower surface of the concrete gravel layer is provided with an anti-seep gravel layer. The anti-seep gravel layer is connected with the concrete gravel layer through steel pipe piles. The steel pipe piles are fixed to the anti-seep gravel layer and the concrete gravel layer. The lower surface of the anti-seep gravel layer is provided with a broken stone hardcore. Reinforcing rods are embedded between the broken stone hardcore and the anti-seep gravel layer. The liquefiable sandy soil structure further comprises vibro-replacement stone columns. The liquefiable sandy soil structure has very high bearing capacity, very high permeable capacity, capable of effectively reducing sedimentation generated after construction as well as improving the liquefying resistance capacity of a foundation and capable of playing a role in water drainage better so that next construction process can be better conducted, and construction efficiency is improved greatly.
