八岔段堤防工程渗透系数室内试验

Permeability coefficient of levee engineering of Bacha through laboratony tests

堤防的渗透破坏可以分为坝基渗漏和坝身渗漏,其中坝身渗漏的重要影响因素之一就是坝身的渗透系数。文章以黑龙江干流堤防八岔段工程为例,通过室内渗透试验,得出坝身的平均渗透系数。以此为依据得出结论,认为该堤坝透水性较弱,防渗性良好。

The seepage failure of the embankment can be categorized into the seepage of its base and body. One of the important factors that affect the seepage of the embankment body is its seepage coefficient. Taken the Bacha project as an example, the mean seepage coefficient has been worked out in this paper by indoor seepage tests, based on which the conclusion that the embankment has low water permeability and high impermeability has been reached.
