摘要
应用^(46)Sc放射性示踪沙技术,根据1989年4月的现场测试结果探讨了淇澳岛东南抛泥区泥沙的运移扩散规律及其对珠海经济特区九洲港航道的淤积影响。实验证明,该抛泥区所抛疏浚泥沙的运移扩散主方向恰是九洲港航道所在的方向。对伶仃水道的疏浚而言,该抛泥地的选择是合理的,但对九洲港航道来说,则存在一定的淤积影响,应采取相应的防淤和减淤措施,以提高港口的经济效益。
In this paper the transport dispersion law of sediments in spoil ground southeast of Qiao Island and the its influence on the siltation in ship channel in the Zhuhai Jiuzhou Port are studied by using radioactive tracer sediment technique 46Sc. Experimentations showed that the main direction of the transport dispersion of the disposed dredged sediment is just right in ship channel direction of Jiuzhou Port. The choice of this spoil ground is reasonable for dredging the Lingding channel, but there is certain influence of the siltation upon ship channel in the Zhuhai Jiuzhou Port. Some steps should be taken to protect against the silting up.
