摘要
针对海底管道交越光缆混凝土软体排铺设工程测量问题,结合上海液化天然气项目海底输气管线工程实例,将RTK-DGPS平面测量和多波束旁扫技术运用到海底铺设软体排的测量中,通过对测量数据的技术分析,所得测量结果的精度和要求符合有关规范,为光电缆保护、海底管道施工以及投产后的安全运行提供保障。
The authors analyze the problem about surveying of soft mattress laying before submarine pipeline crossover optical cable.Based on the Shanghai LNG project undersea gas pipeline project,the RTK-DGPS plan surveying and multi-beam side scan technology are adopted for the soft mattress laying measurement.Through analysis of technical data on the submarine pipeline protection and submarine optical cable,the results can meet standards and the technology can provide protection for the safe operation of the pipeline construction and operation.
