中文摘要:
      软土随着固结压力的增加其渗透性在减小,反映了土样渗透性的非线性特征。且当有效应力达到一定值时,渗透性减小趋于平缓。在曲线图中,大部分土样的渗透性呈现线性递减的关系,部分土样的渗透系数呈现双曲线型和S型递减的关系,不同的趋势关系不仅与原状土样的所处位置有关,也与土样所处的深度有关。
英文摘要:
      The permeability of soft soil decreases with it’s consolidation pressure increases , it reflects the characteristics of nonlinearity of soil permeability .When the effective stress reaches acertain value, the permeability decreases slowly. In the diagram , the most of the permeability of the soil sample renders decreasing at a linear relationship, some soil permeability coefficient of the hyperbolic diminishing and s-type relations, the different trends are not only associated with undisturbed soil sample location, also relevant to the depth of the soil samples.
