以一座高45 m砖结构烟囱爆破拆除为例，介绍了在紧邻高压线、倒塌场地临近学生宿舍等恶劣条件的情况下，高耸结构定向爆破的设计与施工要点，对倾倒方向、爆破窗口、爆破参数和安全防护等进行了精心计算设计，并采取爆破缺口的强力防护及地面减振土堤等有效防护措施控制爆破飞石以及倒塌触地振动对周边建筑物的影响，拆除结果表明烟囱按照设计方向倒塌，定向准确，紧邻的高压线和周围建筑物安全。

Taking a 45 m brick-concrete chimney blasting demolition as an example, the paper introduces the directional blasting design and con-struction points of the high-rise structure under complex poor conditions of closing to high-tension cable and collapsible field closing to students’ dormitories and so on, calculates and design collapsible direction, blasting window, blasting parameters and safety protection, adopts strong blas-ting gap protection and ground seismic reducing embankment and other effective preventive measures for controlling the impact of blasting flying stones and collapsible grounding vibration upon surrounding buildings. The demolition results show that:the chimney collapses at the designed di-rection, the orienting is accurate, surrounding high-tension cable and buildings are safe as well.
