| 摘 要： | 利用声学技术于1992年6月在营口鲅鱼固港进行了疏浚物海上倾倒声学试验。研究了疏浚物倾倒后的沉降、扩散和迁移特性,统计得出疏浚物云团垂直尺度、水平尺度及云团中心浓度与时间的关系式;计算了扩散系数,估算了倾倒后水体中疏浚物悬浮颗粒量;得出了云团漂移方向、距离和影响范围以及云团在海中的长存留时间;进而确定了疏浚物倾倒入海后的物理行为和归宿。

| Abstract: | The acoustic tracking of ocean dumping of dredged-material was performed in Bayuquan Harbor of Yingkou in June 1992 using a high frequency acoustic system. In the experiment the sedimentation diffusion and transportation characteristics of dredged-material dumped were studied. The temporal variation of the vertical and horizontal scales, and the central concentration of suspended cloud of dredged-material were derived by regression analysis. The diffusion coefficient was calculated and the quantity of suspended dredged-material remained in sea water was estimated. The drift direction and distance, the area dispersed and the maximum residence time of suspended cloud were obtained. And the physical behaviour and the fate of dumped dredged-material were then determined. |
