本文用全球卫星接收定位系统 (GPS)与浅地层剖面系统 (Geo Chirp Sub- Bottom Profiler System)对珠江三角洲的铜鼓、伶汀、九州水道海底输油管道掩埋状况进行了勘测 ,全部数据记录在声纳图像增强工作站。经室内回放增强处理得出硬拷贝资料 ,然后将全部定位资料输入计算机用 GIS系统进行处理得出测线的 KP点 ,解释出所测管道掩埋状况。文中列出了管道几种掩埋状况 ,为海洋工程调查研究提供参考。
In this paper, the global satellite receiving positioning system (GPS) and the Geo Chirp Sub-Bottom Profiler System were used to survey the buried conditions of Tonggu, Tingting and Kyushu submarine pipelines in the Pearl River Delta. All the data were recorded in sonar Image enhancement workstation. After the indoor playback enhanced processing to obtain hard copy data, and then all the positioning data input to the computer with the GIS system for processing KP points measured lines, explained the measured buried pipe conditions. This paper lists several buried conditions of the pipeline, providing a reference for the investigation of marine engineering.
