摘    要:对烟筒、水塔定向爆破的切口处进行了受力分析,着重考虑风载作用对倾倒力学条件的改变及对倾倒方向的影响,分析了转角、风载、切口大小之间的变化规律,并根据几个实例进行计算和分析。研究结果表明,风载对筒形高耸建筑物爆破倾倒方向有显著影响,风载增大时,偏转角呈线性增加,同时改变了中心轴的位置。计算时应根据建筑物的形状具体计算。

关 键 词:风载  水塔  烟囱  定向爆破  筒形  高耸建筑物  倾倒

Abstract:This paper analyses the standing force around the blasting cut of a chimney or water tower in directional blasting,especially considers the effect of the collapsing direction while the mechanical condition is varied under wind power.The rules among turnning angle,wind power and the size of blasting cut are analysed,moreover,this paper computes and analyses several examples.The research results indicate that the wind power exerts noticeable effect on tubular tall building.The turning angle is increasing linearly with the increasing wind power,the location of the central line also varies.The wind power is a distributive carload for tubular tall building,so we should consider the shape of the building.
Keywords:wind power  water tower  chimney  directional blasting
