有效提高含浮泥区水域测量精度的方法与实践

The Effectively Method improve Precision of floating sludge water depth survey

在含浮泥较多的水域进行大比例尺水深地形测量,极易因浮泥影响等因素产生水深测量数据的误差。通过对南沙江海联运码头高精度水深测量的实践,分析了定位、浮泥、潮汐、波浪等因素对水深数据误差的影响,并提出在含浮泥水域进行高精度水下地形测绘中应注意的问题及解决措施,以提高其水下地形测量的测深数据精度。

Floating sludge containing more waters in large-scale topographic survey depth,Vulnerable to the impact of factors such as floating sludge generated deviation bathymetry data,Through the practice of Nansha Jianghai transport dock precision depth measure-ments,The influence of positioning,floating mud,tides,waves waves and other factors on water depth data errors,And raised in wa-ters floating sludge process should pay attention to the underwater terrain mapping implementation problems and solutions,Bathymetric data to improve the accuracy of its underwater topography measurements.
