| Abstract: | The stress and deformation characters of Dachaoshan tailwater bifurcated pipe under different working conditions are analysed by means of three dimensional finite element method, and the effects on stress, deformation of pipe line and section reinforcement ratio with the change of caculation parameters, the rock mass defermation modulus and external water pressure discount coefficients is caculated. The figures of analysis offer theory reference for project design and management. |
