Abstract
How to scientifically and reasonably analyze the seepage around the earth rockfill dam which possessed of the strong aquitard around the abutment, the anti-seepage design for this type of earth rookfill dam has a very important significance. Combined with a project, this paper carried out a comparative study of hydraulic and three-dimensional finite element method. The results shown that due to the finite element method avoided the certain man-made assumption, the calculation model much close to the actual, so the results should be more reasonable. At the same time, the research results about the anti-seepage measures showed that there is a positive correlation of lextension length of concrete cut-off wall in abutment with improvement of seepage characteristics around the dam, but its length is more than a certain value, the effect will tend to significantly reduced.关键词
