D river is located in our country southwest, through to its geological, hydrological data, climate analysis, bined with the local building materials, design suitable for the project to help the region to achieve good economic benefit. According to the requirement of flood control, flood regulation putation of reservoir, to determine the crest elevation and release flood waters building size。 through the analysis, on the possible options, determine the hub of the building form, dimensions and water conservancy hub layout plan made in detail。 dam design, through the parison, determining basic profiles and dimensions, make the foundation treatment scheme and the dam body structure, hydraulic, static calculation of outlet structures。 design, choice of building form, outline dimensions, to determine the layout scheme, make detail structure, hydraulic, static calculation. Reservoir with river regulation measures, can greatly reduce the flood on the downstream towns, factories and mines, rural, highway, railway and the tourist attractions of the threat。 create favorable conditions for development of aquaculture. Key words: Dam design； Seepage analysis。 stability analysis。 spillway design。 foundation treatment
