【Abstract】 Based on scaled boundary finite element method,Schur decomposition method is applied to calculate unit earthquake acceleration excited values of arch dam in each direction for different cases with various dam height levels and absorbability factors of reservoir bottoms and bank slope.Then the whole hydrodynamic pressure of dam facing is obtained by considering water compressibility of reservoir.Finally,the influence of dam height levels on hydrodynamic pressure is discussed in detail.更多还原
