对固结系数的非线性变化进行了理论分析,推导了固结系数的非线性控制方程,指出了γ因子对固结系数非线性变化的影响.考虑到固结系数、渗透系数、压缩系数整体变化以及双层软土一维非线性固结方程求解困难,建立了差分格式的双层软土一维非线性固结差分方程,利用差分法对该方程进行了求解,为工程中复杂方程的计算提供了一种新的方法.研究表明:固结系数并不是决定双层软土非线性固结性状的唯一指标,须综合考虑各种因素的影响.

Through the theoretical analysis of non-linear variation of consolidation coefficient, non-linear governing equations of consolidation coefficient were deduced, and influence of γ was studied. Considering the variation of consolidation coefficient, permeability coefficient and compressibility, meanwhile, the consolidation equations were difficult to be solved, one-dimensional non-linear consolidation difference equations of double layer soft soil,which are solved by difference method, was proposed. And it was a new method for complex status function in engineering practice. The mechanical researches showed that consolidation coefficient was not unique index governing the non-linear consolidation behavior of double layer soft soil. Therefore, various factors should be considered systemacally.
