The optimum design of gravity dam

This paper, based on the study on the impervious structure of the dam, puts forward it should reduce the congeal material amount in concrete gravity dam body as far as possible in order to avoid the occurrence of temperature crack. On the basis of analyzing the operation of constructed typical poor and rich RCC dam, this paper puts forward the design concepts for the optimum gravity dam. The dam body concrete only meets the requirements of stresses and stability without seepage control functions and its seepage control functions should be undertaken by the seepage control structures designed specially in the upstream dam surface. The design of dam should embody the principle of function separation.
