| Abstract: | According to the theory of plate shells and the welding contraction model, the calculation formulas of the cylinder shell's welded residual stresses are derived. Using these formulas, the welded residual stresses of the water delivery penstocks are computed. The calculated results provide the theoretical consult for analysing affects of welded residual stresses and designing welding technology of the Three Gorges Project's water delivery penstocks. |
