Embodiments of the present disclosure provide a physical test system of large-scale three-dimensional multi-functional landslide-prevention and control structure. The system comprises a model test tank, a bidirectional servo loading system, a multi-scale model transformation system, a sliding surface evolution visualization system, a positive pressure monitoring system, an artificial rainfall system, and a control system. The bidirectional servo loading system applies a horizontal load and a vertical load, and the multi-scale model transformation system includes a plurality of retractable counterforce brackets, configured to change a width of the model test tank; and the sliding surface evolution visualization system includes a plurality of filming devices, configured to record a whole evolution process of a landslide sliding surface evolution.

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.

Barrier structure for bearing high-energy impact and construction method thereof

A compound of formula (I) or pharmaceutically acceptable salts and/or solvates or hydrates thereof. A process for preparing the compound, a pharmaceutical composition comprising the compound and an application for resisting cannabinoid CB1 receptor are provided.
