在我国,弯曲航道是一种常见的平面形态。由于受弯道形态与地形的影响,弯道处水流条件复杂,流态恶劣,对船舶航行极为不利,是航道整治的重要内容之一。根据河道平面形态和水流特征将弯曲航道划分为单一弯道、连续型弯道、弯曲分汊型弯道3种主要类型。在分析弯道水流特性基础上,指出各类弯曲航道的碍航特点,并进一步以金沙江和尚岩滩、乌江汉口滩典型工程为例提出各类弯道的整治方法和主要工程措施,为今后研究类似工程提供了技术参考。

In China,the bending plane channel is a common form.Due to the shape and topography bend,flow conditions in the bend is complex,flow pattern is very bad,those are extremely disadvantageous to the navigation of the ship,so the bend waterways is an important part of channel regulation.According to river morphology and flow characteristics of the bend waterway,we put it into three main types： single curve,continuous curve and bending braided-type.Based on the analysis of flow characteristics in the curve waterway,hinders navigation channel characteristics of various types of bending waterway are pointed out,and further proposed the major remediation project methods taking the beach of Heshangyan in Jinshajiang River and beach of Hankou in Wujiang River for example.Those provide a detailed technical reference for future work of improving.
