Abstract

Scouring and internal erosion always have created problems for earth dams. So that internal erosion or piping is known as the second causing the earth dam failure. In this study, nanoclay is used as a new additive without environmental problems, to reduce the piping erosion of Silty Sand Soil. To investigate Erodibility samples containing nanoclay with 0, 1, 2, 3, 4, 5and 6 weight percent of dry soil were used and run the Hole Erosion Test (HET). Then the impact of compaction, moisture content and hydraulic gradient on erosion of samples with 1% nanoclay were investigated. The results show that by adding 1% nanoclay erosion rate index increased more than two times, that means the Erodibility reduces. Erodibility of sample containing 1% nanoclay at the most hydraulic gradient was changed from very fast group to moderately slow group.
