On April 12th, the acceptance meeting for the construction project of key scientific and technological infrastructure at the Chinese Academy of Sciences Field Station was held in Dongchuan, Yunnan Province. During the meeting, the large-scale dynamic simulation experimental platform for mountain disasters successfully passed acceptance, officially commencing operations.

The construction of the "Large-Scale Dynamic Simulation Experimental Platform for Mountain Hazards," a key technological infrastructure project of the Chinese Academy of Sciences Field Station Network, was deployed by the Chinese Academy of Sciences. Jointly developed by the Institute of Mountain Hazards and Environment of the Chinese Academy of Sciences, the Hong Kong University of Science and Technology, and China Energy Construction Group, it is currently the world's most advanced experimental platform for physical simulation of mountain hazards, with the largest scale, highest degree of automation in monitoring, and optimal synchronization of systematic data collection.
The platform mainly consists of buildings such as the top platform (including material boxes, material storage platforms, operation platforms, control rooms, and top reservoirs), spillways, and outlet protection platforms. Designed with a service life of 30 years, it can simulate mountain hazards such as landslides, mountain floods, debris flows, and barrier lakes on a maximum scale of 500m3.
The downstream spillway of the platform is approximately 150m long, with a net width of 6m and a depth of 4-5m. The spillway bottom slope adopts two gradients, with the upper section at 32° and the lower section at 16°. Three observation sections are arranged in the spillway section, where experimental devices and observation instruments are installed. A fan-shaped protection platform, 50m long, is connected to the spillway outlet, allowing for the burial and secondary recovery of experimental devices and observation instruments.
After eight years of preparation, design, construction, installation, and debugging, the platform successfully completed the construction of all functional modules of the system platform. On December 13, 2023, it smoothly passed experimental tests, trial operation, and project completion acceptance.
The Large-Scale Dynamic Simulation Experimental Platform for Mountain Hazards is the most representative and advanced scientific research device in the field of disaster reduction in China. In the future, it will become an experimental demonstration base for research, development, testing, application, and promotion of mountain hazard dynamics and new prevention and control engineering technologies, significantly enhancing the level of international mountain hazard research and leading the development of the discipline.
