High-Speed Landslide Impact Test Bench: Simulate, Analyze, and Mitigate Landslide Hazards

Our advanced High-Speed Landslide Impact Test Bench is engineered to accurately simulate high-speed landslide events and critically evaluate the impact range of landslide disasters. The system replicates real-world conditions to study the dynamics of soil and rock debris from waste dumps.

Test Process:
A soil sample trolley, loaded within a 2m x 1m x 1m test box, is accelerated down a 62.5-meter runway to a maximum speed of 15 m/s. An emergency braking command is then applied, simulating a sudden slope failure. This action causes the soil and rock samples to be horizontally ejected from the trolley, providing vital data on the spread and dispersal patterns of high-speed landslide materials.

Facility Specifications:

• Total Coverage: 82.5 meters (L) x 6 meters (W)

• Runway Section: 62.5 meters (L) x 6 meters (W)

• Collapse & Observation Area: 20 meters (L)

• Loading Trolley Maximum Speed: 15 m/s

• Test Box Size: 2m (L) x 1m (W) x 1m (H)

This bench is an essential tool for geological research, risk assessment, and the development of mitigation strategies for landslide disasters.

Purpose: Research into tailings dam failure mechanisms and disaster characteristics through integrated physical simulation.

Methodology:

• Simulates combined failure triggers: platform tilt, intense rainfall (≥400mm/24h), and underground seepage.

• Induces dam breach through controlled hydraulic erosion and internal saturation.

This Rock Mass Plane Similarity Model Test Rig is designed for geotechnical research on major projects like hydropower plants, cross-sea tunnels, nuclear waste storage, and deep mining. It simulates rock mass behavior under complex stress conditions, providing critical data for design validation and disaster prevention in large-scale underground engineering.
