南水北调引江济汉取水口区河工模型试验研究

Experimental study on river model of water intake area of diverting water from Yangtze to Hanjiang River of S-N Water Diversion Project

通过南水北调引江济汉工程取水口河段河演分析和引水渠进口段河工模型试验,重点研究了三峡工程蓄水运用后取水口河段河道演变规律,引水渠流速流态、进水闸消力池消能情况和沉沙池、沉螺池工程效果等。研究表明:三峡运行初期,取水口河段河势变化不大,对取水工程有利,其研究成果可供工程设计单位采用或参考。

Through fluvial analysis of water intake reach and river model experiment of the entrance of diversion canal of diverting water from Yangtze to Hanjiang River, the study emphasized on fluvial law, velocity and flow pattern of diversion canal, energy dissipation of stilling basin of entrance and engineering efforts of desilting basin and snails retention tanks after the impoundment of TGP. The results show that in the initial period, the river regime changes little in the reach, which is beneficial for the diverting project. The results can be adopted and referenced by engineering design departments.
