Aiming at the actual situation that perilous rock aggregate can easily avalanche under action of excitation at rupture of perilous rock on steep and high slope, this work generalizes perilous rock aggregate with nonthrough vertical fissure as a prism. A vibration mechanics model at rupture of perilous rock aggregate under the excitation was deduced and established using the wave theory. To solve the model through the characteristic method, four equations specific to any mass point in perilous rock aggregate were obtained, respectively, vibration equation, displacement equation, stress equation and vibration velocity equation. Model experiments in laboratory identify that the error between the theoretical solution and experimental data is about 6.13%.
