| Abstract: | The large uneven subsidence of the large diameter circulating water pipes of 900 MW units during the construction process is introduced.The bending,deformation,and stress of the pipe section with the smallest curvature radius are analyzed,and the causes are studied.The treatment suggestions and the theoretical support are given,recommending the necessary measures that should be adopted in design and construction of large diameter circulating water pipes. |
