摘要
为查明海底管道的位置和掩埋状态,在海底管道检测中使用多波束测深技术。介绍了多波束的系统组成、调查方法和数据处理等内容。重点对数据处理进行了论述,提出了确定海底管道位置和掩埋状态的分析方法,并对影响多波束检测效果的频率、波束角和水深等因素进行了探讨。通过分析认为,与单波束相比,多波束在海底管道检测中具有直观、高效和高分辨率的特点,具有较好的工程应用前景。
In order to interpret the pipeline position and quantify the pipeline settling depth, multi-beam echo sounding techniques are used in the pipeline inspection. Multi-beam system components, installation calibration, survey method and data processing in the pipeline inspection are introduced. The data processing of the multi-beam echo soundings and some special data analyses in order to interpret the pipeline position and quantify the pipeline settling depth based on DTM are stressed. Some factors, such as frequency, beam angle and water depth, influencing the resolution of the multi-beam echo sounder are also discussed. The analyses suggest that the multi-beam echo sounder has higher resolution and is more effective and visual in comparison with the single beam echo sounder. The use of multi-beam sounding techniques should become more prevalent in view of their numerous advantages over single beam systems in submarine pipeline inspection.
