Abstract

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.
