Abstract

The effectiveness of seepage cutoff and sliding stability of an earth levee reinforced by soil cement deep mixing technology (SCDM) was evaluated by field monitored data. Groundwater observation was conducted via nine ground water wells installed in the research site. Lateral displacement of the whole earth levee was measured by the 15-m inclinometer casing and a 0.5-m inclinometer probe. The research assessed effects of soilcrete reinforcement by comparing with simulations before applying widely in the Mekong Delta, Vietnam. The results indicate that the soilcrete walls can effectively prevent the seepage through the earth levee’s body and improve the factor of safety about 1.2 times.
