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。
In June 1992, the acoustics technology was used to dredge the sea dumping acoustic test of dredged material at Yingkou anchovy harbor. The sedimentation, diffusion and migration characteristics of dredged material after dumped were studied. The relationship between the vertical scale, horizontal scale and concentration of cloud center and the time of dredged material cloud was obtained. The diffusion coefficient was calculated and the dredged material The amount of suspended particles, the direction, distance and influence range of cloud drift and the long residence time of cloud in the sea were obtained. Then the physical behavior and fate of dredged material after dumped into the sea were determined.
