摘要 本文首先建立了三维情况下考虑土体各向异性的固结微分方程,进而对任意初始孔压情况下三维问题固结微分方程进行求解,并通过算例与各向同性情况下的解进行了比较,得出了一些有价值的结论. This paper first sets up a three dimensional consolidation diffrential equation considering anisotropy of soil, and then gives the solution of this diffrential equation under arbitrary initial pore pressure condition.The solution in anisotropic condition is compared with one in isotropic condition and the difference is discussed. Based on this, some valuable conclutions are drawn finally.
