Experimental simulation of spiral slip lines on granular materials
- 43 Downloads
The experimental results of modeling geomedium around a mine working are reported. Two families of spiral slip lines are reproduced on a granular material. One or two families of log spiral slip lines arise around a cylindrical foreign body simulating a supported mine working. It is shown that shears on the lines of different families develop irregularly.
