摘　　要：通过分析连云港的泥沙特性以及港口淤积现状,对连云港主航道的适航水深的应用进行了研究,并结合室内的流变试验和船模阻力试验确定了适航重度值;同时利用双频测深仪、音叉密度计等仪器对连云港主航道开展了现场实船测量,分析了适航资源的分布情况以及船舶对浮泥的扰动情况,为连云港港区适航水深资源的利用提供了技术支撑。研究结果表明:连云港主航道的适航淤泥重度值为12.2 k N/m^3;主航道、港池泊位浮泥分布较为均匀,适航厚度基本在10~15 cm范围内;船舶在航行过程中对浮泥产生了一定的扰动,船体尾部出现较为明显的浑浊带。The application of nautical depth in the Lianyungang main channel was analyzed by the analysis ofsediments characteristics and deposition situation. Connected with rheological test and ship model resistance experi-ment, the nautical density was confirmed. Furthermore, the field measurements were carried out by the double fre-quency detector and tuning fork densimeter in the main channel to find out the spatial distribution of nautical re-sources and the disturbance of fluid mud caused by navigation. The research result shows that： the nautical densityin the channel of Lianyungang main channel is about 12.2 k N/m^3. The fluid mud is distributed equally in the mainchannel, harbor basin and berth, and the thickness of fluid mud is ranged from 10 cm to 15 cm. The fluid mud is dis-turbed when ship is sailing in the channel which caused the reduction of water depth, and at the stern of the ship,turbidity zones are appeared at the surface of ocean.
