摘　　要：以长江河段南京大胜关水下抛石实施为例,阐述双频识别声纳水下抛石监测技术及工作原理,结合双频识别声纳测量成果,对水下抛石护岸型式运行效果进行分析。结果表明,所监测区域整体以淤积为主,局部护岸冲刷,在坡脚处冲刷较为剧烈,后期需加强观测,防止冲刷破坏加剧。双频识别声纳水下监测技术可为进一步推广应用先进的水下探测方法提供依据及借鉴。Based on the implementation of underwater riprap in the Dashengguan area of the Yangtze river in Nanjing,this paper introduces the dual frequency recognition sonar monitoring technology and working principle of underwater riprap.Combined with the measurement results of the dual frequency recognition sonar,the operation effect of the underwater riprap revetment type is analyzed.The results show that the monitored area is mainly dominated by sedimentation,with local bank protection erosion.The erosion is relatively severe at the foot of the slope,and observation needs to be strengthened in the later stage to prevent further erosion and damage.The dual frequency recognition sonar underwater monitoring technology can provide a basis and reference for further promoting the application of advanced underwater detection methods.
