摘要
为解决渗透压力作用下软粘土的渗透诱发固结问题,建立了一维渗透诱发固结有限应变理论的数学模型,针对该模型所需参数,主要是高塑性粘土和其他细颗粒土的固结本构关系,即压缩性关系(e～σ′)和渗透性关系(e～k),进行了渗透诱发固结试验和分析。通过试验得到软粘土的渗透系数与孔隙比,有效应力与孔隙比的关系表达式。
This paper presented one-dimensional seepage-induced finite strain consolidation theory to solve the consolidation of very soft soil under seepage stress. To determine the parameters needed in this model, the consolidation constitutive relationship of high plastic soft clay and other fine-grained soil, the seepage-induced consolidation test and analysis were provided. The expression of permeability and void ratio (e-σ'), the effective stress and void ratio relationship (e-k) of this kind of soil could be deduced from the test.
