A method for calculating surge waves caused by toppling dangerous rock masses, based on wave-making machine theory, targets the most dangerous conditions of a toppling dangerous rock mass. The toppling dangerous rock mass is simplified as a rectangular rigid block, and the maximum surge wave amplitude is assumed to occur during the rock mass's toppling. Using differential theory, a torque balance equation is established for the entire rotational process of the dangerous rock mass.

The toppling process is then simplified to multiple shaking-plate wave-making machines generating regular waves at different times and locations. These regular waves are then superimposed and summed as the surge wave for the toppling dangerous rock mass, ultimately determining the maximum surge amplitude for the toppling dangerous rock mass.
