英文摘要	Here, the typical impact load of debris flow was chosen, and a reinforced concrete dam against debris flow was simplified into a cantilevered beam, its dynamic partial differential equation was established. Then, the variable separation method in mathematical physics equations and the modal superposition method in the structural dynamics were used to get the analytical solution to the dynamic partial differential equation. According to the mechanics of materials, the corresponding stress and strain of the beam were obtained. The example analysis showed that the analytical solution to the dynamic equation is reliable, and the top of the dam against debris flow has the largest displacement. The study results provided an idea for practical engineering mechanical calculation. ©, 2015, Chinese Vibration Engineering Society. All right reserved.
