Effects of internal erosion on mechanical properties of soil

Abstract

Internal erosion causes various ground disaster such as sinkhole accidents and landslides, those are supposed to happen due to water penetration in the ground. In this research, triaxial test apparatus which are capable of causing internal erosion inside the specimen was developed. Eroded specimen was sheared in drained condition. It was found that at axial strain within 5 %, soil stiffness was decreased due to even small degree of erosion.
