文章结合烟囱倾倒拆除对邻近住宅建筑安全影响评估的工程实践 ,简述了反应谱法的评估方法 ;介绍了采用模态分析技术 ,在现场检测住宅建筑基本周期的方法步骤 ;讨论了结构输入激震的确定方法。本文介绍的思想和方法对今后其它施工震动影响的现场检测分析工作具有参考价值 In this paper, the assessment method of response spectrum method is briefly introduced in combination with the engineering practice of the assessment of the impact of chimney dumping on the safety of neighboring residential buildings. The method steps of using modal analysis technique to detect the basic cycle of residential building on site are introduced. Determine the method. The ideas and methods introduced in this paper have reference value for on-site testing and analysis of the impact of other construction vibrations in the future
