摘要:
非通航孔桥抗冲击能力较差,抵御船舶撞击能力较弱,易造成桥梁结构失效。目前,相对于非通航孔桥墩,通航孔桥墩设计了各种类型的防船撞装置,并应用于众多桥梁结构上。然而,非通航孔桥按照通航孔标准进行防撞设计是不现实的。近年来,非通航孔拦截系统的研究工作较少,对现有几种不同类型的拦截系统进行分析,对比工作原理、适用条件等,为今后非通航孔桥拦截系统的工程应用提供参考依据。以宁波舟山港非通航孔桥为背景,结合航区环境、经济因素等,采用消能重力锚自动下落式浮基高架拦截系统。通过能量法进行消能分析,有限元软件ANSYS/LS-dyna进行船舶撞击拦截系统动态模拟,结果显示该拦截系统可有效拦截船舶。
Abstract:
The shock resistance of the non-navigable bridges is week, easily causing structural failure and destruction. At present, various anti-collision facilities apply in the navigable piers. However, the anti-collision facilities of the navigable bridges are not suitable for the non-navigable bridges. There are only a few researches on interception systems of non-navigable bridges. Considering the working principles and characteristics, various intercepting systems were analyzed. The interception system of automatic drop-type floating base with the energy-dissipation gravity anchor was installed in the Ningbo Zhoushan non-navigable bridge. The energy method and finite element software ANSYS/LS-dyna were conducted to analyze the energy dissipation. Results showed that the ship could be effectively intercepted by the interception system.
