【摘要】 基于大量工程实践积累的经验及数据,对浅地层剖面仪在海底管道检测中的影响因子,包括不同信号源、不同航行速度及不同水深时的探测效果进行比较后认为,实际应用中,采用Chirp技术的浅地层剖面仪有较好的探测效果,保持适中航速是有益的,随着水深增加,探测效果会随之受到影响。更多还原

【Abstract】 Based on a huge mass of field data and experience accumulated from projects,the influence factors when using sub-bottom profiler in pipeline inspection were analyzed,including different signal sources,different sailing speed and different depths.The authors concluded that the sub-bottom profiler with Chirp technology has good inspection effect in practice while the speed is moderate.The inspection effect will be influenced with the depth increasing.更多还原
