摘　　要：在戴家洲右缘崩岸特点、崩岸机理分析的基础上,通过戴家洲右缘崩岸敏感性计算,分析了戴家洲右缘崩退与直港航道条件的关系。根据直港合理曲率半径以及崩岸敏感性计算结果分析了护岸时机,确定了对戴家洲右缘下段先进行守护,而戴家洲右缘上段待时机成熟后再行守护,并提出了先期护岸长度。对长江中下游已有护岸措施及其适应性进行了分析,在此基础上,提出了合理的护岸措施。Based on the analysis of riverbank collapse characteristics, mechanism of Daijiazhou reach in middle Yangtze River, combined with the sensitivity calculation, the relationship between radius of curvature and channel condition was analyzed. According to the results of reasonable radius of curvature and sensitivity calculation, the revetment timing was analyzed as follows： Firstly, riverbank protection of the lower segment of Daijiazhou was carried out, and after timing and the conditions were ripe, the upper segment of revetment again. The revetment length in advance was put forward. The revetment protection measures in middle and lower Yangtze River and its adaptability were also analyzed. The reasonable bank protection measures were presented.
