PLATFORM FOR SIMULATING DANGEROUS ROCK COLLAPSE OF SURROUNDING ROCK IN UNDERGROUND ENGINEERING, AND SIMULATION SYSTEM AND METHOD

摘要

A platform for simulating a dangerous rock collapse of surrounding rock in underground engineering, and a simulation system and method, the platform comprising four vertical reaction walls (1); the multiple reaction walls (1) enclose to form a square reaction space, and an opening at the lower ends of the reaction walls (1) is provided with a base (3); a side of each reaction wall (1) close to the reaction space is provided with a row of horizontal stress loading plates (5); and reaction beams (2) are provided above the reaction space. The reaction beams (2), the stress loading plates (5) and the base (3) enclose to form a loading space, and the loading space is used for placing a surrounding rock simulation block to be tested. The stress loading plates (5) can move horizontally in the normal direction of the reaction walls (1), and the reaction beams (2) can move in the vertical direction, thus the loading of the surrounding rock simulation block is completed. The stress loading plates (5) and the reaction beams (2) are each driven by a linear motion unit so as to move.
