Abstract

Selected the typical impact load of debris flow, and forward the ferroconcrete Dam against debris flow was reduced to a cantilever beam, set up the dynamic partial differential equation, and then used the variable separation method in mathematical physics equation and modal superposition method in the structural dynamics, obtained dynamic solution of partial differential equation. According to the mechanics of materials to, we can get the corresponding stress and strain. The example analysis shows that the analytical solution of dynamic equation is reliable, and in Dam against debris flow has the largest displacement of dam crest, provides an ideal for practical engineering mechanics calculation.
