渗流作用下土石坝防渗探讨

Discussion on embankment dams seepage prevention under seepage flow effect

简述了土石坝被广泛应用的原因,研究了土石坝渗流问题的方法,探讨了土石坝地下水渗透数学模型的选用,指出实际工程中需建立一套新的运动微分方程,以解决非稳定渗流情况下大坝应力变形及防渗问题。

The reason of embankment dams was utilized comprehensively was discussed,the embankment dams＇ seepage problem method was studied,and the embankment dams＇ underground water seepage mathematical model selection was discussed.It pointed out that the practical engineering need build a set new sport differential equation so as to resolve the dam stress deformation and seepage prevention problem of unstable seepage situation.
