doi:10.3969/j.issn.1674-0696.2014.01.22

Abstract

Abstract: Fluid mud often appeared in harbor basins and navigation channels in muddy coast areas and caused the shoaling of navigable depth , which affected the judgment of nautical depth and might cause serious results such as ship grounding. The problem of fluid mud resulted in field observation and the progressing of observation technology made it possible to accurately acquire the key properties of the fluid mud including thickness , rheological properties and density. It provided an essential support to analyze the source , composition , movement characteristics and formation mechanism of fluid mud. And different field observation technologies for fluid mud were classified and introduced. The advantages and disadvantages were then briefly analyzed. The SILAS system represents the developing trend of fluid mud observation because of it' s visual and reliable data , which is essential to navigable depth study.

Key words: fluid mud, field observation, three-wings-lead;γ-ray, dual-frequency depth sounder, tuning fork, SILAS

摘要： 淤泥质海岸地区的港池及泼深的航道内容易产生浮泥层，造成通航水深的减小，影响适航水深的判断，严重时会导致船舶搁浅。浮泥问题的提出正是源于现场观测的结果，测量技术手段的不断进步为准确获得浮泥层的厚度、流变特性、密度等关键参数，深入研究浮泥的组成来源、运动特性及形成机理提供了重要支持。对浮泥现场观测技术进行了分类及介绍，并简要分析了各观测方法的优缺点，认为以SILAS 系统为代表的搞合观测系统代表了今后浮泥现场观测的发展趋势，该方法所得数据直观、可靠且连续，可为研究浮泥分布、确定适航水深等问题提供较为准确的依据。
