摘要
亭子口水利枢纽是嘉陵江干流开发的控制性工程 ,控制流域面积 6 2 5 5 0km2 ,具有防洪、灌溉、发电、航运、水产养殖等综合效益。亭子口水利枢纽库区泥沙模型 ,干流上起广元市上西乡 (2 9号固定断面 ) ,下迄大清沟(15号固定断面 ) ,河段长约 6 5km ;模型模拟范围为水库常年回水区上段及整个变动回水区。通过亭子口水库常年回水区上段及整个变动回水区的泥沙模型试验 ,对 3种水库调度方案即 45 6m方案、45 8m(1)方案、45 8m(2 )方案库区泥沙淤积情况、洪水位的抬高以及航道条件等方面进行分析研究 ,为确定水库的正常蓄水位和水库调度原则提供科学依据。
Tingzikou hydroproject is a key project for the main stream development of Jialing river,controls a drainage area of 62 550 km 2,and possesses the comprehensive benefit of flood control,irrigation,power generation,navigation,aqua-culture etc..The reservoir sediment model of Tingzikou hydroproject simulates the main stream sediment condition,with a river stretch of 65 km.The simulated range of the model covers the upper section of perennial backwater zone and the whole fluctuated backwater zone of the reservoir.Through the sediment model test,the analyses on sedimentation in the reservoir,the rising of flood level and navigation condition etc.are carried out for 3 reservoir regulation schemes,i.e the scheme of normal pool level 456 m,458 m(1),458 m(2),which provides scientific basis for the determination of the reservoir normal pool level and the reservoir regulation principle.
