Abstract  

A method for submarine pipe status inspection in strong tide region was proposed based on submarine acoustic exploration technologies aiming at the problem that submarine pipe is more dangerous and cannot be inspected by conventional methods. The method chose side-scan sonar system, sub-bottom profiler, and multi-beam echo-sounder system to detect the spatial relationship between the pipe and the seafloor. The submarine pipe status inspection process was designed after a brief introduction to the working theory of every selected technology. Then the acoustic data acquisition and processing based on spatial reference were explained. Finally two ways to express the inspection results were proposed, namely the two-dimensional expressing way based on diagram and the three-dimensional expressing way based on ArcEngine component from ESRI．

强潮地区海底管线状态检测方法研究——杭州湾海底管线状态检测

针对强潮地区海底管线危险性大、且无法用常规方法进行检测的现状,提出一种基于海底声学探测技术的强潮地区海底管线状态检测方法,考虑到海底管线状态检测的主要目的是确定管线与海床面之间的空间关系,该方法选择了侧扫声纳系统、浅地层剖面仪和多波束测深系统等海底声学探测技术.在简要介绍了每种技术的工作原理之后,进行了海底管线状态检测流程的设计,并介绍了各类声学数据的采集过程和基于空间参考的声学数据处理方法,最后提出两种检测成果表达方式,即基于图表二维表达方式和基于ESRI公司的ArcEngine组件的三维表达方式.
