【摘要】：淤泥质海岸地区的港池及浚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系统为代表的耦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。
[Abstract]:In the muddy coastal area, the ponds and the dredged channel are easy to produce the floating layer, which results in the decrease of the navigable water depth and affects the judgement of the seaworthy water depth. The problem of floating mud is caused by the results of field observation. The continuous progress of measurement technology means to accurately obtain the thickness, rheological characteristics, density and other key parameters. In this paper, the composition, motion characteristics and formation mechanism of floating mud are deeply studied. The observation techniques in situ are classified and introduced, and the advantages and disadvantages of each observation method are briefly analyzed. It is considered that the coupled observation system represented by the SILAS system represents the development trend of the field observation of the floating mud in the future. The data obtained by this method are intuitionistic, reliable and continuous, and can be used to study the distribution of the mud. The determination of seaworthy water depth and other issues provides a more accurate basis.

【正文快照】： 通常认为,浮泥是一种主要存在于淤泥质河口海岸地区常见的自然现象[1-2],是贴近底床的一层流动性很大的高含沙水体,与上层水体之间有明显的分界面。C.C.Inglis,等[3]在研究Thames河的泥沙运动时最早使用了“Fluid Mud”一词。在20世纪50年代,我国科研人员研究天津新港回淤问题
