摘　　要：为准确掌握乌江渡水电站新建机组发电尾水池底板及左右边墙现存状态,采用多波束探测技术联合水下机器人进行高质量水下全覆盖安全检测,获取高精度、高分辨率的水下地形数据和构建物直观图像,以查明尾水池底部冲刷破坏程度和左右边墙性能。结果表明,新建机组发电尾水池底板和左右边墙虽存在淤积、水生物附着、墙面麻面结瘤等问题,但程度均较轻,影响较小。多波束联合机器人能获得翔实水下地形数据和直观图像,能准确判断待测区域淘刷破坏程度和构建物性状,可为类似工程水下安全检测分析研究提供参考。Multi-beam detection technology joint underwater robot is adopted for high quality underwater complete coverage security detection in orderto accurately grasp the existing state of tailwater pond baseplate,the left and right side walls of new generating units in Wujiangdu Hydropower Station,thereby obtaining underwater terrain data and building visual images with high accuracy and high resolution,and finding out the tail tank bottom scouring damage degree and the performance of the left and right side walls.The results show that there are some problems on the tailwater pond baseplate,the left and right side walls of the new generating units,such as siltation,aquatic organism attachment,nodulation on the wall surface,etc.,but the degree is not serious and the influence is not significant.The multi-beam joint robot can be used for obtaining detailed underwater terrain data and visual images.It can be used for accurately judging the extent of scouring damage and properties of structures in the to-be-tested area,which can provide reference for similar underwater safety inspection and analysis.
