摘要
为了实现对海洋平台海底地基形位进行高效精细测量,基于多波束测深原理研制了拥有自主知识产权国产首套海底地基形位测量仪;文中给出海底地基形位测量仪的工作原理、系统组成,设计方案和主要关键技术,并在对该设备进行水池测试的基础上进一步开展了JZ20-2MUQ石油钻井平台海上外场实地测量试验研究,并对测量数据进行了细致处理获得了平台桩腿受冲刷影响形成的坑形信息;与传统潜水员探摸结果进行比对的结果表明该设备技术先进、测量结果有效可信,可以为海洋平台地基基础测试分析与安全评估提供重要的桩基形位信息。
To survey seafloor groundsill＇s shape and position for sea platform effectively and subtly, the first homemade seafloor groundsill＇s shape and position surveying equipment with independent intellectual property rights was developed based on multibeam bathymetry principle. The principle, development and composition of the seafloor groundsill＇s shape and position surveying equipment were introduced, its design scheme and key techniques described, and an aborative sea experiment conducted based on its successful test in pool. In the experiment, the seafloor groundsill of JZ20-2MUQ offshore drilling platform was surveyed in detail, and the shape information of the pit scoured was achieved through data processing. Comparison with the results groped by diver shows the equipment＇s reliability, effectivity and ability to meet the needs of the measurement and safety evaluation of oceanic engineering platform＇ s seafloor groundsill.
