摘要
介绍采用FE-101型双频道回声测深仪和γ射线测沙仪等在连云港庙岭港区进行的大量关于浮泥层厚度、分布等特性的测试情况和调查内容。根据国外研究浮泥的经验,确定“适航深度”τy为3Pa左右。从连云港淤泥流变特性方程τy=4.95038×10-6ρ2·27确定浮泥“适航深度”的重度值为12.5kN/m3左右,并提出利用双频道测深仪低频上界面作为浮泥“适航深度”的测量和校正方法。
Abstract This paper introduces the application of FE-101 dual-frequency channel-echo-sounder and γ -ray sand-measuring meter to Miaoling Area of Lianyungang Port,including a great deal of examinations of fluid mud thickness and distribution characteristics,etc.. Based on these examinations and referring to foreign experience ,the navigable depth τ y, is determined as about 3 Pa.And from the mud rheological behavior equation in Lianyungang, τ y =4.95038×10 -6 ρ 2·27 , the force density of the mud relevant to navigable depth is determined as 12.5kN/m or so.The author also puts forward to use the upper interface of low frequency of the dual-frequency channel-echo-sounder as the survey and correction methods for the navigable depth of mud.
