中文摘要: 通过实地调查和气象资料分析,得出造成1999年8月30日亳州市教育电视台电视铁塔倒塌事故的气象原因是由于受飑线袭击,铁塔承受了超过满足国家GBJ9-87所规定的铁塔设计风速,此外铁塔位于形成喇叭口形状的两座高楼中的一座上,两座高楼由于特殊结构而形成狭管效应,造成局部风速增大,使铁塔所承受风速比开阔地的风速还要大,从而造成倒塌事件。根据这一分析,得出一些有益结论,能对高层建筑与铁塔建筑设计规范的修正提供借鉴意义。
Abstract:The collapse of TV iron tower of the teaching TV station at Bozhou,Anhui province on 30 August 1999 is caused by a squall.The iron tower endured much great wind beyond the limit criterion in GBJ9 87.Additional,the iron tower locates on one high building near to another high building,these two high buildings form a ′hom′ that makes the wind speed swifter than otherwhere,the high speed wind collapses the TV iron towere.This conclusion is beneficial to the study of high building and iron towere building criterion.
