【摘要】 桥梁防撞装置中有主要防御船撞桥墩的、船撞上部结构的;有在撞上时桥墩直接受力的和桥墩不直接受力的;有只保护桥的和既保护桥又保护船的等各种不同分类法。本文着眼于主通航孔以外的辅助墩、过渡墩、水中引桥墩等的防撞,这部分桥墩通常占有较宽的水面,是小船的航道。本文提出一种方式是:既能拦住大船又不妨碍小船通行,而且能在几百米范围内为水中各墩防撞的柔性缆索吸能方式。本文阐述其原理、措施和某些重要的细节。更多还原

【Abstract】 This paper focuses on the protection of the piers out of the main navigable spans,including assistant pier,transition pier and bridge approach pier in water area. These piers normally have lower strength than the main piers and occupy large water area,which is the route of boats and yachts. So,this paper brings forward a new protection method. It can not only hold up big vessels,but also let boats and yachts pass. It protects all piers in this water area within the scope of several hundred meters by means of flexible cables. This paper introduces the theory,measures and some important details for the design.更多还原
