摘　　要：初步分析了黄土与砂土在液化机理、孔压增长模型、体积压缩系数以及渗透系数方面的差异以便认识黄土液化具有的孔压增长快、消散慢和沉降大的特性。The differences between loess and sand in liquefaction mechanism, models of pore water pressure generation, coefficients of volumetric compressibility and permeability coefficients are preliminarily analyzed to realize the characteristics, the rapid increase, slow dissipation of pore water pressure and large settlement during loess liquefaction.
