数值分析在防渗帷幕时效性分析中的应用

The numerical analysis application in the research on Curtain Grouting

利用数值分析的方法确定出帷幕的渗透系数与渗漏量的关系,进而对帷幕的防渗效果进行分析。通过现场压水试验得到当前防渗帷幕的透水率,并对其防渗效果进行评价,将现场试验结果与数值分析结果对比,发现数值计算结果与现场试验结果一致,因此该数值分析方法可以用于对研究区内防渗帷幕时效性评价。

A numerical analysis method is proposed and used to determine the relationship between Permeability coefficient and leakage of the curtain.Through the field water pressure test, the seepage rate of the current waterproof curtain is obtained, and the seepage prevention effect is evaluated.The field test results compared with the results of numerical analysis, it is found that the numerical results are consistent with the field test results, so the numerical analysis method can be used for the evaluation of the timeliness of the impervious curtain in the study area.
