项目摘要

The storms that occurred in late March 2004 (with a relatively short return period of one or two years) clearly illustrate the vulnerability of urban areas to wind induced damaged. In various urban conurbations numerous trees and advertisinghoardings failed, causing widespread disruption to the UK rail and road network. The wind borne debris present in these storms, due to both the failure of large items of street furniture/trees and unsecured items on the ground being lifted intothe air, caused serious damage and destruction. For example, one person was killed as a result of wind-borne debris in Leicester and two died as a direct result of being hit by parts of a tree in Blundeston, near Lowestoft in Suffolk (BBC,2004b). Unfortunately these events are not uncommon. For example as a result of the earlier storms of October 2000, with roughly the same return period, several people died and two were seriously injured. In the recent BirminghamTornado much of the damage to buildings, and many of the injuries to people, occurred because of flying debris. Even in minor wind storms wind-borne debris can be a significant problem. This project aims to undertake a series of measurements on instrumented items of debris as they fly through the air. The data obtained from these tests will be used to improve and develop numerical models which will be of use to designers.

2004年3月下旬发生的风暴（重现期相对较短，为一两年）清楚地说明了城市地区易受风致破坏的影响。在多个城市，大量树木和护栏倒塌，导致英国铁路和公路网络大范围中断。由于大型街道设施/树木的故障和地面上未固定的物品被提升到空中，这些风暴中存在的风载碎片造成了严重的破坏和破坏。例如，在莱斯特有一人被风吹来的碎片砸死，在萨福克郡洛斯托夫特附近的布伦德斯顿有两人直接被树的一部分击中而死（英国广播公司，2004年b）。不幸的是，这些事件并不罕见。例如，由于2000年10月早些时候的风暴，重现期大致相同，造成数人死亡，两人重伤。在最近的伯明翰龙卷风中，许多建筑物的损坏和许多人的受伤都是由于飞行碎片造成的。即使是在小风暴中，风载碎片也可能是一个严重的问题。该项目的目的是对在空中飞行的装有仪器的碎片进行一系列测量。从这些试验中获得的数据将用于改进和开发对设计人员有用的数值模型。
