摘要
近年来东北水道上三号洲尾部至新坝一带崩岸严重，下三号洲左缘滩地不断冲刷后退、岸坡崩退，导致河宽明显增加，实施航道整治工程十分必要。在河床演变分析的基础上，结合物理模型试验成果，探讨东北水道整治工程效果：方案实施后，东北横水道过渡段航道尺度可达到4．5．1×200m×1050m（水深×宽度×弯曲半径）的治理目标，
In recent years, Dongbei waterway beach Ⅲ to Xinba coastline collapses seriously, and the left edge of beach Ⅲ continues to wash back, which leads to a significant increase in the river width. Based on the analysis of river bed evolution, and combining with physical model test results, we discuss the effect of waterway regulation of Dongbei waterway in the lower reach of the Yangtze River.After the implementation of the regulation engineering, Dongbei waterway＇ s channel scale can reach 4. 5 m × 200 m × 1050 m.
