Research on impervious earth material for Nouzhadu rockfill dam with core wall

A lot of experimental study and project analogy showed that it is necessary for the earth material as seepage control material to adopt the earth mixing gravel in the Nuozhadu project. Meanwhile, the proportion of gravel material and the degree of compaction for earth material have been preliminarily determined. Based on the analysis of test results, this paper puts forward the project parameters of earth mixing gravel for the Nuozhadu project. The research results showed that the earth material on the selected site when some engineering measures are taken can meet the requirement of the earth material for seepage control of the rockfill dam with core wall with the height of 260m.
