| 摘 要： | 针对安康枢纽回水变动区重点碍航浅滩段的河道特点,分析了柏果滩至雁子石滩河段在上下游枢纽运行前后的水文变化。采用定床水流河工物理模型的研究手段,研究了不受枢纽调节影响的天然状态水流特点和碍航因素。依据枯水期浅滩局部通航水深不足、水面比降较大等碍航因素,结合回水变动区航道整治原则,确定了相应的整治方案。通过一系列优化措施,使河段航道通航水流条件达到了Ⅵ级航道通航标准。

| Abstract: | Based on the waterway characteristics of main navigation-obstructing shoal at fluctuating backwater area in Ankang Hydro-junction,the hydrological changes between Baiguo shoal and Yanzishi shoal after hydro- junction operation were studied.The flow characteristics in natural state and the navigation-obstructing factors were analyzed by means of fixed-bed river flow model.According to the navigation-obstructing factors of navigable water depth deficiency and large water surface gradient, a regulation scheme was confirmed combining with the principle of waterway regulation at fluctuating backwater area.The navigable conditions can reach the standards of the fourth class after a series of optimization measures. |
