摘　　要：以魏村双线船闸工程为依托,以工程中23 m口门三角船闸为研究对象,提出了一种新型防撞结构体系对其进行有限元建模。并在1000 t的船舶,行驶速度为1.4 m/s,撞击角度为6°这种最不利的计算工况下研究新型防撞结构体系的动力响应分析,并和传统的刚性防撞结构体系进行对比。研究表明:刚性防撞结构体系在计算工况下会出现破坏,而新型防撞结构体系工作状况良好;在轻质、更换和消能方面新型防撞结构体系更具有优势。Based on the Weicun two-line ship lock project,this paper studies the anti-collision structure system of a 23 m gate triangle ship lock.By comparing with the traditional rigid anti-collision structure system,the dynamic response analysis of the new anti-collision structure system is studied under the most unfavorable calculation conditions of a 1000 t ship with a travel speed of 1.4 m/s and an impact angle of 6°.The study shows that the rigid anti-collision structure system could be damaged under the calculated working conditions,while the new anti-collision structure system works well.This implies that the new anti-collision structure system has more advantages in terms of light weight,replacement and energy dissipation.
