【正文】 nal design calculation method and calculation of verification. 3 Personal opinionReservoir flood control reservoir flood regulation by the role of two different ways, a flood, flood storage effect on another. Reservoir irrigation effect, increase the frequency of the geological disaster, caused the reservoir sediment deposition, the land, the soil salinity downstream. The reservoir and downstream water quality deterioration, the river water quality change.寧可累死在路上，也不能閑死在家里！寧可去碰壁，也不能面壁。 (3) simple structure, reliable operation, easy to maintenance heightening or expanding。t play, and it will endanger the safety of the downstream. As a result, the design, construction, management must be resolutely carry out this basic principles to ensure dam safety.Dam type many, according to the high dam and pattern classification is as follows:(a), in accordance with the dam height were classified:Can be divided into three classes of low dam, zhongba, high dam, dam is less than 30 meters : dam for 3070 meters high dam, dam in 70 meters reservoirs is generally low dam.(2), according to the type of classification:Can be divided into earth dam and gravity dam and arch dam, buttress dam, etc. My county on small reservoirs are earth and rockfill dam is a kind of local material dam, which is posed of earth, stone, or the generation by rolling into a water retaining structure, the dam type is widely used in water conservancy project. In our county, 140 small reservoirs, all for earthrock DAMS. At present this kind of dam type is the main reason of the wide scope of application: (1) dam materials can use local materials。s case, probably twice, in one hundred after a one hundred did not e to pass. Small reservoirs in the flood control standards of earth and rockfill dam: small (a) type reservoir level of main building to level 4, the design flood control standard is once every 30 to 50 years an
