摘　　要：为了准确高效地完成港珠澳大桥项目东、西人工岛填海工程的填海竣工海域使用验收测量,研究了一种基于CORS与高清侧扫声呐的水下验收测量技术。该技术使用侧扫声呐的固定式安装方法,结合CORS高精度定位测量技术,提高了海上定位与海底地形测量的精度,高效地完成了人工岛填海的水下与陆地测量工作。结合工程实例,阐述了人工岛填海边界确定的方法。通过多波束水深测量数据与侧扫声呐数据的对比验证,并使用控制点校核测量进行了精度分析,证明了该技术的可靠性。与传统海域使用测量方法相比,该技术可以大大提高测量精度,在类似海洋工程中具有应用价值。Taking the Hong Kong-Zhuhai-Macao bridge artificial island project as an example,the underwater acceptance survey technology with side scan sonar and CORS was introduced in this paper.The accuracy and efficiency of marine positioning and seabed topographic measurement were improved through application of this technology.The method of determining the reclamation boundary of artificial island was expounded.The reliability of this technology was proved by a comparison with multi-beam bathymetric data and an accuracy analysis of control point measurement.Compared to traditional sea area measurement method,this technology can greatly improve the measurement accuracy,and has application value in the sea area measurement.
