Application of drip test for study the erosion of earthen wall by rainfall – case of Le Havre area, France

Abstract

    This paper presents the influence of the properties of soil of earthen wall of constructions on its durability to erosion by rainfall. An improvement Drip Test was used to simulate the affects of rainfall on the erosion resistance of earthen wall. For the soil without binder, it found that, soil erosion decreases in power with an increase of dry density and an increasing linear relation between soil erosion with compaction water content was established. A correlation between soil erosion with liquid limit and percentage of clay was found, it showed that erosion depth achieves a minimal value at certain value of liquid limit as well as percentage of clay, it mean soil erosion was a quadratic function of liquid limit and percentage of clay
