摘要
Abstract
Rapid cross-flow exists in the navigable channel under a bridge limits the navigation of large construction vessels,and restricts the overall construction efficiency.Based on the navigable channel at Xiashanyong in Shenzhen Sanpao expansion Project,it was proposed to set a flow control curtain by hanging rubber pipes,which could effectively reduce the cross-flow velocity in local water area.The calculation and review results showed that net channel width met the real navigable requirements for ships up to 1 000 DWT.Thus the tonnage of navigable ships could be increased temporarily subject to the limited conditions.The above measures improved the traffic efficiency,served as a reference for other projects.关键词
