摘　　要：102 m高烟囱濒临河道、紧邻深基坑施工场地,结合其结构和构造特征的查勘与检测,设计了梯形切口的定向窗、放倒窗、定位窗及切口圆心角和高度等参数,并按烟囱整体放倒拆除要求进行了受力分析,提出了相应的钢筋混凝土烟囱机械破拆措施,为烟囱机械定向放倒拆除提供了成功工程案例。This peper analyzes the structure and constructed features of the 102-metre high chimney which is near river and closes to deep pit construction venues. Essential factors are designed, such as the directed window with trapezoidal incision, dismantling window, positioning window, central angle of incision and height. Force analysis is also done as required by chimney overall demolition. Measures are put forward for RC chimney machinery demolition as successful engineering cases in this paper as well.
