【正文】 ontrol standard, can be divided into the design and calibration standard, usually expressed in the flood return period. Return period is refers to the runtime, flood, on average, how many years, such as design criteria onceinacentury, refers to an average of one hundred appeared once more than the standard of flood, this is from longterm39。 Small (2) type reservoir level to level 5, main building design flood control standard for 20 years, check the flood control standard for the 200 a. The main building of the reservoirsIn small reservoir project, the main building for the dam, spillway and the culvert. Below we give introduction to the structure and construction respectively. DamDam is a water retaining structure, its role is to intercept river, saving water, raise the water level, in order to satisfy the irrigation, water supply, power generation and the need of other departments of national economy, it is the main body of reservoir engineering. It make the reservoir benefit not only the crash can39。 (2) is able to adapt to the foundation deformation。 (4) construction technology is simple, less working procedure, is advantageous for the mechanized rapidly the construction. SpillwaySpillway is drainage buildings for an outlet excess floods, prevent flood accident, therefore spillway is actually a security door, spillway layout according to its position, can be divided into the riverbed spillway spillway or Banks of the river. Riverbed spillway was built using the original bed the putation of flood, it is not only the water retaining structure, and drainage structures. The spillway, set the spillway in the Banks of the river. Small reservoir dam generally for earth and rockfill dam, dam body are not allowed to flood, so many type spillway with the Banks of the river. Banks of the river type spillway can be divided by different forms of water flow into the spillway is sp
