摘要(Abstract)：

介绍了在复杂环境下对某电厂发电机组排架结构主厂房和两座钢筋混凝土烟囱实施一次爆破拆除。对主厂房两侧山墙采用时差、爆破切口高度、预拆除及钢丝绳捆绑相结合的综合措施,有效地控制了两侧墙的外翻。叙述了主厂房和两座钢筋混凝土烟囱的爆破设计和安全防护措施。爆破后,厂房与烟囱迅速按设计方向倾倒,周边建(构)筑物及设施安然无恙,取得了良好的爆破效果,达到了安全、精细和快速爆破的目的。为以后类似爆破工程提供了参考。
Simultaneous demolition blasting of the main workshop of generating units and two reinforced concrete chimneys in a power plant was introduced under the complex conditions.Comprehensive measures to the gables on both sides of the main workshop were taken such as such as the time difference,blasting cut height,pre-demolition and steel wire ropes tied,which effectively controlled them toward out collapse.Moreover,blasting designs and protective measures of the main workshop and two reinforced concrete chimneys were described.The main workshop and chimneys dumped rapidly according to the design direction after initiation and surrounding buildings and facilities were safe after blasting.Good blasting effect was achieved.Safe,precise and fast blasting purpose was reached.The experiences of the project provided some references for the future similar blasting projects.
