- 摘要:
- 海底抛石范围的精确测量，对于海上抛石工程质量检测、障碍物警戒区划定及船舶航行安全保障具有重要意义。参量阵浅地层剖面仪可探测泥面上下的障碍物，鉴于其在海底管道和线缆测量中由点到线的应用特点，类比提出将点-线-面思想应用于抛石范围测量。通过解析参量阵浅地层剖面仪的工作原理，结合现场数据质量影响因素分析，选择合适的测量参数，实现对抛石层范围的调查。某码头的实际应用验证了浅地层剖面法在抛石层范围调查中具有很好的适用性，可为同类工程提供技术参考。
Accurate measurement of submarine stone dumping areas is of great significance for the quality inspection of marine stone dumping projects, the delineation of obstacle warning zones, and the safety guarantee of ship navigation. The parametric sub-bottom profiler can detect obstacles both above and below the mud line. Given its point-to-line application characteristics in submarine pipeline and cable surveys, this study analogically proposes to apply the point-line-area concept to stone dumping area measurement. Through the analysis of the working principles of the parametric sub-bottom profiler and factors affecting field data quality, suitable measurement parameters were selected to achieve the investigation of the stone dumping layer area. The actual verification at a certain wharf demonstrates the strong applicability of the sub-bottom profiling method in surveying stone dumping layers, providing a feasible technical reference for similar engineering projects.
