Provided are a system and a method for impact testing and monitoring of a high-energy flexible net. The system includes a vertical impact testing unit, a slope impact testing unit, an impact simulation unit, and an impact monitoring unit. The vertical impact testing unit includes a vertically positioned gravity wall. The slope impact testing unit includes a wall slope positioned perpendicularly to a second side of the gravity wall. A first side of the gravity wall and a slope surface of the wall slope are securely provided with a flexible net, respectively. The impact simulation unit includes an impact assembly and a lifting assembly. The impact monitoring unit is configured to monitor a deformation result and an internal force change result of the flexible net.

Systems and methods for impact testing and monitoring of high-energy flexible nets

A barrier structure for bearing a high-energy impact and construction method thereof are provided. The barrier structure includes a supporting pile array arranged between two opposite mountain slope surfaces. The supporting pile array is arranged in a straight line and includes two or more supporting piles. The two or more supporting piles are fixed at a lower part of a mountain. A barrier net is connected to the two or more supporting piles. The barrier net passes through the supporting pile array and extends to the two opposite mountain slope surfaces. The barrier net is fixed on the two opposite mountain slope surfaces. Pull plates are disposed on the two opposite mountain slope surfaces, and one side of each of the pull plates is fixed to a corresponding slope surface of the two opposite mountain slope surfaces through reverse prestressed anchor cables.
