Meanwhile, shock isolation technology is widely used in industrial equipment to control vibration and noise during operation of the industrial equipment.

[0003] Shock isolation technology adds a layer of shock isolation device at the bottom of a building to concentrate the displacement generated during an earthquake in the shock isolation layer with smaller stiffness, and converts the energy released by the earthquake into kinetic energy of the overall structure for dissipation. Since the shock isolation structure needs to concentrate displacement in the shock isolation layer, a shock isolation trench is usually set around the building according to the displacement requirement. Generally, the width of the shock isolation trench is usually greater than the displacement that may occur in the shock isolation layer. However, in some special cases, such as extremely rare earthquakes exceeding the shock isolation design, near-fault earthquakes with large energy release, the occurrence of such special cases may cause the shock isolation structure to collide with the shock isolation trench.
