Abstract：The settlement process of high fill channel is difficult to predict in the south-to-north water diversion project. The influence of filling height H，elastic modulus E and Poisson's ratio on the channel were clarified with ANSYS FEM. The lateral deformation correction coefficient K1 and the additional settlement correction coefficient K2 were proposed，and the compression modulus of filled soil was corrected during the loading process. And a calculation method which was applicable to the settlement process of high fill channel was established on the basis of layered summation method. The settlement of channel based mainly on the consolidation settlement Sj in the process of grading load Pi which mainly produce creep deformation Ss when the grading load Pi remains constant. The method has less calculating parameters，and the impact of the lateral deformation，the additional settlement and the compression modulus changing with depth are considered. The settlement process and the total settlement，which start from the channel filling until stable during the post-construction settlement，could be properly calculated out by the method. A visualization application was compiled based on the calculation method in Matlab7.0，which could reasonably simulate and predict the settlement process of high fill channel under the application of grading load，and provide a quick and practical guidance for the design and construction of high fill channel.
