由于拆除爆破中建筑物塌落触地振动过程具有复杂性，为了得到塌落振动主频率，利用量纲分析方法，建立塌落振动主频率与建筑物质量、建筑物重心高度、震中距等主要影响参数之间的函数。通过结合东西方向现场实测数据，利用回归分析法，得到特定爆破条件下塌落振动主频率的预测公式。通过对比南北方向现场实测数据，得出减震沟能提高建筑物后座触地振动频率，同时降低后座触地振动速度。为类似拆除爆破工程主频率的预测及相关安全减震措施提供了理论和实际依据。

Due to the demolition blasting of buildings collapsing touchdown vibration process is complex,in order to get the main frequency of collapse vibration,the dimension analytical method was used to establish the function re-lation between vibration frequency and main influence factors of the building mass,the center of gravity height of buildings,epicentral distance,etc. By combining field data east-west direction,gain the main frequency forecast for-mula of collapsing vibration under special blasting condition. By combining field data north-south direction,damping groove can improve buildings backseat touchdown vibration frequency;at the same time reduce the backseat touchdown vibration speed. The theoretical and practical bases are provided for forecasting main frequency and rele-vant safety shock absorption measures of similar blasting engineering.
