为了解钢筋砼高耸烟囱爆破倾倒过程中各相关部位应变及应力变化的情况，也为类似爆破烟囱倾倒拆除的参数设计提供可参考的第一手基础数据，确保倾倒方向的准确性，对3座拟爆的100 m高钢筋砼结构烟囱的支撑体相关部位布置了测点。爆破时进行应变观测，取得了一系列时间-应变数值。据此进行应力分析，总结了该情况下钢筋砼烟囱爆破倾倒过程中支撑体相关部位应力变化规律。

The measurement spots in the relevant parts of supports of a 100 m-high reinforced concrete chimney were laid out to ensure the accuracy of collapse direction and to investigate the stress and strain of every parts in the course of collapsing the tower reinforced concrete chimney.Series of time-strain data are recorded when observing the blasting process, thus the stress variation law of the relevant parts of suppurts when the reinforced concrete chimney was blasted can be obtained on the basis of the measured data.
