多波束倾斜安装方法在极浅水界址测量中的应用

Application of Multi-beam Oblique Installation Method in Extremely Shallow Water Boundary Point Survey

针对多波束垂直安装方式无法精确测量临岸极浅水区域水下界址的难题,提出了多波束倾斜安装方法,制作多波束倾斜支架,通过倾斜安装多波束增加向陆一侧波束数量,实现临岸极浅水区域水下界址测量。海南某人工岛水下界址测量结果表明,多波束倾斜安装方法很好地解决了极浅水区域水下界址线测量问题,校准后多波束水深成果精度满足规范要求,可广泛应用于极浅水区域水下界址和水下地形测量工程。

Aiming at the problem that the vertical installation method of multi-beam can not accurately measure the underwater bound-ary site in the extremely shallow water area near the bank,a multi-beam oblique installation method is proposed,and a multi-beam oblique bracket is made.By installing oblique multi-beam,the number of the landward beam is increased,and the underwater bound-ary point survey in the extremely shallow water area near the bank is realized.Based on the survey results of underwater boundary site of an artificial island in Hainan,it is shown that the multi-beam oblique installation method can effectively solve the survey problem of underwater boundary line in extremely shallow water area,and the accuracy of multi-beam depth results after calibration meets the re-quirements of the specification,which can be widely used in extremely shallow water area underwater boundary site and underwater to-pography survey engineering.
