Dynamic Finite Element Analysis of a New Type Flexible Rock Shed under the Impact of Rock Block and Improving the Design

Figure 21

Deformation of the rock shed obtained by the experimental and numerical simulation. (a) Deformation of the rock shed when the block is in contact with the rock shed. (b) Deformation of the rock shed when the block falls in the lowest point. (c) Deformation of the rock shed when the block is still rebounding and steel-vaulted structure stops rebounding.
