Abstract
Some portions of levee in the Red River delta, located in north of Vietnam, have frequently been damaged by seepage failures. Therefore, a countermeasure of reinforcement for seepage failures are needed to be applied. The countermeasure using natural fiber material is considered to be effective in the Red River delta, because rice farms are flourishing and natural fiber material such as the straw is available at low cost. The purpose of this study is to evaluate the countermeasure of reinforcement by examining the resistance against seepage failure of short fiber mixture soil with natural material. Due to the shortage of soil material in the Red River delta, material was prepared under the simulation of grain size distribution in the Red River delta. The resistance against seepage failure of short fiber mixture soil and fiberless mixture soil are prepared ,respectively. As a result, reinforcement in soil material was confirmed to be effective when the percentage content of sand was over 68.
