On the basis of specifying the basic design data of 0 1 water control project, this paper determines the layout scheme of the project by consulting the relevant engineering design standards and the design manual of water control project, and works out the control elevation and basic dimensions of the main buildings with the help of basic calculations such as drying calculation and blowout calculation, and calculates the stability of the building through the arch beam method. On this basis, combined with the design standards, the main buildings are redesigned in detail. This design specification includes the basic design data of Hubei -0 1 water control project and the calculation process of determining the layout, architectural modeling and detail design of the whole project, which is a preliminary design of the project.

The whole article consists of nine chapters (with an appendix). The first chapter is an overview, which mainly introduces the basic situation of the project; In the second chapter, according to the hydrological characteristics of the dam site, the hydrometeorological survey of Hubei -0 1 key projects in the river basin, especially near the dam site, is introduced. The third chapter is the topographic and geological conditions of the hub and the reservoir area, especially the topographic and geological conditions of the dam site near the dam axis. The fourth chapter is the selection of hub buildings and hydrological calculation, including the determination of hub engineering grade, building selection, adjustment calculation, drawing up the cross-section size of blowouts and preliminarily drawing up the hub layout scheme; The fifth chapter draws up the size and dam layout, including the determination of shape and beam section, the layout of seepage control and drainage facilities of dam foundation, the plane layout of dam body and the analysis and calculation of stress stability; The sixth chapter is flood discharge design, mainly including dam crest details and downstream energy dissipation design; The seventh chapter is the design of the explosion building, mainly focusing on the detailed gate layout of the entrance building and the energy dissipation design of the hole depth and exit; The eighth chapter is the design of power plant guidance system and power plant building, mainly the design of power plant guidance system and power plant building; Chapter 9 is about foundation treatment, including foundation excavation, cleaning, consolidation grouting, curtain grouting and all the treatment measures. The appendix mainly explains the calculation involved in the design part of each chapter in detail.
