| Abstract: | Thick beds, large blocks and horizontal beds are the features of thick - bedded sandstones. Once the fall occurs, the harm will be greater. This paper analyzes the fall instability mechanism of thick-bedded sandstone according to the basic principles of engineering geology, and uses RockFall simulation software to simulate the motion trajectory and energy changes of sandstone fall. |
