【Abstract】 Three-dimensional elastic-plastic FEM method is adopted to calculate the dam stress and deformation of the Dongping hyperboloidal arc dam with multi-load combinations under multiple conditions. The result shows that the stress and deformation of the arc dam accord with the general rules of the calculation of FEM. Furthermore, equivalent stress check shows that the error of calculation is within the allowable range of specification.更多还原
