Steady Seepage Analysis of the Filled Channel Slope with Anisotropy

Abstract

Middle Route of South-to-North Water Transfer Project main canal is grand supplied channel, it has the high requirements for transfer water reliability, so seepage control is particularly important for the channel slope along canal. According to conditions of seepage field and transformed relations of permeability coefficient to respectively simulate the seepage of channel slope with the homogeneous isotropic seepage field and the homogeneous anisotropic seepage field, the mathematical model and finite element model were created for the seepage of the filled channel slope with stratified and rolled, using ANSYS thermal analysis module for steady seepage analysis. Compared analysis shows that the seepage of the stratified and rolled channel slope in homogeneous anisotropic of seepage field is more intense than in homogeneous isotropic of seepage field, the analysis of the stratified channel slope by the homogeneous anisotropic seepage field matches the actual and is also more reasonable.
