Abstract

Internal erosion causes various ground disaster such as cave-in accident, slope failure and etc., which is supposed to happen due to water penetration under the ground with severe rainfall. Especially in well-graded material, initially finer particles flow out and this flow makes drained water turbid, which has been considered as a warning of the ground failure. However, relationship between turbidity of drained water and internal erosion is not very clear. In this research, characteristics of internal erosion were evaluated from turbidity of drained soil by one dimensional column test. The test was conducted under various water penetration conditions simulating practical situations.
