摘要
长江口北槽是上海港的通海航道,年疏浚量高达1000×10~4m^3以上,且航槽淤积有逐年增加的趋势。本文从航道河势状态相似性出发,通过状态相似关联度,建立灰色模型GM(2·1),揭示多因素作用的航槽状态相似性发展过程,作出航槽近期淤积量的预报.为疏浚部门制定疏浚生产计划提供依据。
North channel in Yangtze Estuary is one of sea-leading -waterways of Shanghai Harbour, in Which yearly dredging volume reaches over ten million cubic meters, and tends to.increase year by year.Based on channel situation and stage similarity relational grade, a GM(2.1)is set up.It reveals the course of development of channel similarity under the action of various factors, and forecasts the siltation volume in the nearest future a.s the basis of dredging planning for relevant dredging departments.
