水下爆破载荷引起坞门振动响应试验研究

Study on Vibration Response of Floodgate to Loading Produced by Underwater Blasting

通过研究水下爆破载荷引起挡水坞门的振动响应,探讨了坞门不同部位和方向上的振动特性,利用FFT变换对气泡帷幕减震作用进行了分析。

This Paper studies the vibration response of floodgate to the loading which is produced by underwater blasting, and discusses the vibratary character of different areas and different directions. By means of FFT alternate, their frequency spectrum analyses are carried out which are related to reducing vibration of bubble curtain.
