    UNCOUPLED SOLUTIONS FOR ASYMMETRIC CONSOLIDATION OF A MULTI-LAYERED SOIL WITH COMPRESSIBLE CONSTITUENTS

    • 摘要: 采用Schiffman和Fungaroli提出的位移函数,从非轴对称可压缩地基固结的基本控制方程出发,引入中间变量,通过对坐标θ的Fourier级数展开,关于坐标t、r的Laplace-Hankel变换,得到了6×6阶和2×2阶两组非轴对称固结问题的非耦合传递矩阵,然后利用传递矩阵法,结合层间连续性条件和边界条件,得到了多层可压缩地基非轴对称固结问题在积分变换域内的解耦解。最后应用Laplace-Hankel逆变换技术,得到了该问题在物理域内的理论解。编制了相应的计算程序,并进行了数值计算与分析,讨论了可压缩性对地基固结过程的影响。

       

      Abstract: Starting from the governing equations of asymmetric consolidation of soil with compressible constituents, together with the intermediate variables, the technique of Fourier expansions with respect to coordinate θ, Laplace-Hankel transform with respect to time t and coordinate r, two sets of uncoupled transfer matrixes of 6 order and 2 order for a single layer soil with compressible constituents are acquired after using the displacement functions suggested by Schiffman and Fungaroli. Based on the continuity and the boundary conditions, the transfer matrix method is utilized to derive the uncoupled solution for the multi-layered soil with compressible constituents in the transform domain. By the inversion of the Laplace-Hankel transform, the solution for the consolidation of a multi-layered soil with compressible constituents in the physical domain is obtained. Numerical analysis is carried out by the computer program, and the effect on the process of consolidation for the compressibility of pore fluid is also discussed.
