混凝土面板堆石坝局部止水缝失效渗透稳定分析
Seepage stability analysis of concrete faced rock-fill dam under the cases of local seal seam failure
摘要
Abstract
The impervious face of concrete faced rock-fill dam is easy to get failed.Once the im-pervious face fails,it can produce an important effect upon the infiltration rate,flow and slope gradient,accordingly,it is necessary to study an appropriate calculation method,for the dam body engineering geological conditions are rather complicated.The professional finite element software SEEP-3D for computing seepage flow-in combination with engineering real examples is used with the traditional numerical calculation method to calculate the water head distribution seepage flow dimensions and phreatic line position of the single vertical seam failure in different positions and to make the contrast with the analytical solution so that the results have found that the seepage flow is not in coincidence with the seepage laws.For this reason,based on the tradi-tional numerical calculation method,this paper suggests a kind of numerical calculation method (i.e water head boundary should be applied to the failed seam positions downstream respectively) whose calculation results are found to be in very good coincidence with the real engineering exam-ples and analytical solution.Accordingly,the research results can provide the references for the seepage-proof design of concrete faced rock-fill dam.关键词
