Tao River Embankment Gannan Zhuoni County Town Of Section

Tao River is the upper reaches of the Yellow River,a large tributary of the rising in Gansu and Qinghai provinces junction West Dumping Hill Donglu,flows through the Luqu,Lintan,Zhuoni,Minxian,Lintao,Dongxiang,join the Yellow River Liujiaxia Reservoir in Yongjing county.River is full-length 673.1km,watershed area 25527km2,Heyuan elevation 4260m,at the mouth of the elevation 1629m,by the effect of Liujiaxia reservoir water level,in fact,below the mouth 1735m for in the reservoir area.The relative elevation of 2631m,the whole river average ratio dropped to 2.8 per thousand.Zhuoni county is located in the south of the Gansu Province,Gannan Tibetan Autonomous Prefecture in the southeast,the county a total area of 5419.68 square kilometers.Zhuoni county is located in the Tao River shore,most of the city is located in the Zhuo Gou Mizoguchi pluvial fan,part of the city is located in the south of the Tao River.Tao River bridge across the north and South County,surrounded by green hills,the Taohe River water passing through the city.The paper closely combines the Tao Tao River basin hydrological station years observed flood data and historical maximum flood composition of not even a series of order,derivation of governance of each section of the section design flood,and levee project area landform,stratum and lithology,geological structure,engineering Taohe river current status and existing problems of analysis,and the evolution of rivers and river facies analysis calculation,according to the design principle of the embankment,Levee Revetment scheme were technical and economic comparison,through calculating the correlation to determine the technical parameters related to dike engineering.The main research contents are as follows:1 on the basis of Tao River Basin,several hydrometric station,mainly on the annual runoff,flood,sediment analyses.2 according to the results of hydrological analysis,the river bed stability calculation,as well as the bed flow,the stability of river width and the distance of the embankment,3 according to the design principle of embankment,Levee Revetment scheme for technical and economic comparison.4 through the calculation of water surface profile,scour depth calculation,levee superelevation calculation,determine the relevant technical parameters of levee project.5 according to the city has been built to build the embankment design drawings,and the geological data in the control,a reasonable basis for the embankment reinforcement.6 on the concave section of the flow oblique thrust more powerful,design with a diversion,revetment,erosion and river stability of spur dike.
