Study On Programming Schemes Of ZHALINCHUAN Small River Valley Dams Department Engineering Construction

The text describes the district to the loess plateau mound gutters area moderate breezes sand area of natural condition in Zhalinchuan, Dahe town , Yulin, Shaanxi province, and economy, society environment, the present condition of water and soil conservation manages , the ditch a dam department engineering to construct the present condition of inquisition research, this text is from the loess plateau mound gutters area Zhalinchuan Small river valley natural environment, the humanities environment, and the present condition of the silt dam, flood control ability, the existed problem etc., analyzed the condition of silt dam construction and the realistic function: manage the soil erosion and reduce sediment into the yellow river, resolve "three agricultures "s problem. On the base of fully consider the present condition of dam department construction, resources of setting up the dams, transportation, material for building the dams, technique power and mass foundation etc. according to the two greatest targets: yellow river water and soil conservation ecosystem engineering construction , flood control, and produce silt ground. According to the foundation of silt dam and relevantly technical specification, design two different construction projects, after contrast analysis argument of flood control ability, assurance harvest ability , economic performance etc. Choose a set of project which can't reduce the dam control area, can't reduce the flood control standard, can't reduce the numbers of the framework dam but can add up the scale of the framework dam and it can be used in the local water and soil conservation ecosystem engineering construction. This project can greatly control the flood, satisfies the local farmland construction, economic performance is higher and it match the natural condition of Zhalinchuan and social circumstance. The research , the text not only for the scientific construction project of Zhalinchuan small river valley , but also provides the worthy reference for designing the dams department the construction project of the excessive district of the similar sandstorm area and the loess plateau mound gutters area.
