摘要: 该文通过对未加固与水泥土桩加固模型地基振动台试验，再现了未加固和水泥土桩加固模型土体宏观液化现象，分析了未加固和水泥土桩加固模型土孔隙水压力、孔压比及承压板沉降的变化规律，得出水泥土桩加固液化土地基不仅能够提高地基土的抗液化能力，也能抑制桩间土体的沉降。

Abstract: By the shaking table test, the macro-liquefaction of the foundation reinforced by cement-soil piles and the one unreinforced was observed. And the variation law of the pore water pressure，the pore water pressure ratio and settlement of the foundation were analyzed. It is found that the soil-cement column could provide a beneficial effect both on the resistance to liquefaction and reduction of subgrade settlements.
