Study On The Flood Control Engineering For Sujiawan-heichengzi Section Of The Main Stream Of Zuli River

Zuli River is the upper reaches of the Yellow River is a tributary of the, basin, Gansu Province is located in the central, East meets the Ningxia Hui Autonomous Region, South set in Tongwei County, Yuzhong County, Lanzhou West and adjacent to, between east longitude 104 degrees 12 '--105 degrees 30', north latitude 35 degrees 17 '- 36 degrees 34' between, the area 10653km~2. Zuli River from south to North north-south throughout the Huining, flows through the Jingyuan Da Lu, Ulan two Xiang, Jingyuan County, West trapdoor empties into the Yellow River, stream length, 224 km. The Governance section in the middle and lower reaches of the river in Dalu Township, the territory, were arranged 12 segments, administers segment length 21.419 km and new embankment 10.429 km, the slope 1.405 km, revetment 9.024 km, protect 0.95 million population, cultivated land 0.813 million mu.Under the precondition of ensuring the width of the river flood, take economic and reasonable engineering measures, make governance river formed with a certain scale of flood control system, improve the overall capacity of flood control, reduce the river erosion, collapse of bank failure and land inundation loss, reduce soil erosion, reduce the coastal villages and towns and farmland under the standard of design flood disaster loss. According to the Zuli River Basin in the three hydrological station hydrological data, and levee engineering address topography, engineering Zuli river current situation and existing problems of analysis, and the evolution of rivers and river facies analysis calculation of Levee Revetment scheme of 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 according to the hydrological data of the existing hydrological stations in the river basin, the hydrological analysis is carried out; 2 according to the results of hydrological analysis, the river bed stability is calculated, and the calculation of the bed flow, the stability of the river and the determination of the treatment of the lead and the distance of the bank; 3 according to the actual topography and geomorphology of the hydrological, meteorological and geological data, the river management scheme and the selection of the scheme are selected; 4 Calculation of the technical parameters of the embankment building; 5 evaluation of social and economic benefits after the completion of the project.
