A arch dam using the technology of roller compacted concrete RCC on Muli River , in the construction process of arch dam, crack control requirements are higher. If we can find a kind of relatively superior dam partition form, by inducing joint transfer and stress release, to ensure the integrity of arch dams. In this paper, reference similar works, in combination with Shapai arch dam " 85 " and " 95" key research results for the arch dam [1][2], put forward three kinds of joints design: transversely arranged four induced joint scheme, transversely arranged two induced joints and peripheral stress release seam scheme, transversely disposed three induced joint scheme. Applicated of ANSYS software, revealed three joints design of the dam body stress, displacement and distribution characteristics in normal conditions. On the basis of this, by overloading to model failure, different joint forms of dam failure process and failure mode, according to the scheme of the stress, displacement and overload characteristic comparative analysis, recommended a relatively superior arch dam joint programmes, for engineering design and construction of reference.
