| 摘 要： | 浮码头趸船靠泊位移和锚链张力的确定十分困难,目前尚无行之有效的方法。结合悬链线经典理论,运用物理及力学方法,通过分析浮码头正常靠泊情况下能量的传递途径推算趸船的运动幅度和锚链张力,以供类似工程参考。

| Abstract: | Since the 175 m test-operation of the Three Gorges Resevoir (TGR),the typical reach in the fluctuating backwater area has suffered navigation problems because of the pebble movements,among which the Sanjiaoqi reach is particularly serious.Located on the Jiulongpo harbor,Sanjiaoqi reach is a typical gully and branching reach,and the main channel is bend,narrow,shallow and dangerous.As a result of the change of the sediment movement law due to the impoundment of the TGR,new characteristics appear.The amount of sediment deposition is small,while the influence on the channel conditions is relatively large,and a lot of ships are stranded during the sluicing period.To improve the channel conditions,maintenance and dredging are extremely necessary.Based on the field measured data,we study the characteristics of sediment movements and discuss the dredging plan and effect. |
