摘要:

天津新港抛泥地的泥沙运动以往研究较少,其泥沙运动对航道的影响不详。本文利用现场实测资料,对抛泥区的潮流特征、泥沙运动规律作以分析研究。并首次在国内试用了中子活化技术对底沙运动进行了示踪测定。

The sediment motion in spoil site of Tianjin Xingang port was less studied in the past,it was not clear how the sediment motion influenced on navigation channel. Making use of measured data in—situ, this paper carried out analysis and investigation on the tidal current characteristics in spoil area and the regularity of sediment motion. Neutron activation technique was first tried to make tracing measurement for bed—load movement.
