1 工程概况多浪渠水库位于新疆兵团农一师塔里木北岸灌区上游,控制灌溉面积2.7万hm~2,于1965年兴建,库容1100万m~3,经1972年扩建后,设计库容达到4500m~3.由于该水库没有设库外引水渠,洪水期自塔里木河拦河闸引水的含砂量较高,造成水库淤积严重.另外,每年5～6月,水库放水闸的最大泄水量只有25m~3/s,不能满足灌区作物灌溉用水要求。因 1 Project Overview The Duolaquu Reservoir is located in the upper reaches of Tarim Beiliu Irrigation District of Nongyi Division of Xinjiang Corps. It controls irrigated area of ​​27,000 hm ~ 2 and was built in 1965 with a storage capacity of 11 million m ~ 3. After its expansion in 1972, the designed storage capacity reached 4500m ~ 3. Because there is no external diversion canal in the reservoir, the sand content of water diversion from the Tarim River during the flood period is relatively high, resulting in serious siltation of reservoirs. In addition, the maximum discharge of reservoirs in the reservoir is only 25m ~ 3 / s, can not meet the irrigated crop irrigation water requirements. because
