摘要
长江上游以滩多、礁险、流急、水乱著称,在长达1 000余km范围内有200多个碍航滩险。急流滩在长江上游航道中虽不是最多的碍航滩险,但有急流滩的位置通常都会成为卡口或控制河段。近年来对长江上游多个急流滩险实施了治理,取得了显著的成果。对典型急流滩险的碍航特征和整治思路进行总结,以期为今后长江及其他大型山区河流急流滩险航道治理提供参考。
There are more than navigation-obstructing rapids within the 100 meters scope ot the upper Yangtze River. Although rapids reaches are not the most navigation-obstructing ones, reaches with rapids usually tend to be the bottle neck or control reach. In the recent years, regulations have been carried out to many rapids on the upper Yangtze River and remarkable achievements have been achieved. This paper summarizes the navigationobstructing features and regulation ideas for typical rapids, hoping to provide reference for rapids regulation in mountainous rivers.
