| Abstract: | The research on the stability of diversion dike and cofferdam of nuclear power station has been developed by introducing the finite element numerical simulation method and the finite elements strength reduction theory and method based on design optimization and comparison of cofferdam and diversion dike. The most disadvantage section is selected to do the stability analysis checking by considering seepage, fluid-solid coupling effect and strength reduction （SSR）,which can verify the actual engineering clearly, and the research results can provide technical guidance for similar projects. |
| Keywords: | diversion dike and cofferdam strength reduction stability seepage fluid-solid coupling field shear |
