摘要
为了提高检测过程中对悬空海底管道的辨识能力,基于调查数据,系统分析总结了海底管道悬跨的多种声学检测方法,如侧扫声呐、单波束测深系统、浅地层剖面系统及多波束测深系统等,比较了各种检测方法的应用条件,分析了造成海底管道悬跨的多种成因机制,并通过数值计算演示了管道周围局部冲刷中的孔道冲刷的动力过程。
In order to improve the detection ability of suspended pipeline,based on survey data,the varies kinds of acoustic detection methods and their applicable conditions were researched,such as side-scan sonar,single beam echo sounder,sub-bottom profiler and multi-beam echo sounder,etc.The genetic mechanism of subsea pipeline free-spans was analyzed;the dynamic process of channel scour in local scour around pipeline was demonstrated by numerical calculation.
