Abstract
Internal erosion of the soil usually accompanies loosened soil around it. The degree and area of the loosening are dependent on the type of soil. In uniform sand, soil around the internal cavity expands and a lot of voids develop in the loosened area. On the other hand, for sand with fines, fine particles escape between coarse grains.
In this study, loosening in the uniform sand was simulated and the mechanical properties of loosened sand were evaluated by triaxial testing.[This abstract is not included in the PDF]
