在地表条件恶劣的地区进行地震工作时,人们都把激发条件的选择和研究看得十分重要。本文试图从频谱的角度出发,分析了炸药震源、爆炸索和可控震源的频谱,提出可控爆炸的设想。可控爆炸激发的震源频谱也相当于一个带通滤波器。可控爆炸可借助于一个特制的可控爆炸机来实现。
When conducting earthquakes in areas with poor surface conditions, it is very important that people choose the stimulus conditions and study them. This paper tries to analyze the frequency spectrum of dynamite, explosion cable and vibroseis from the perspective of spectrum and put forward the idea of controllable explosion. The source spectrum excited by a controlled explosion is also equivalent to a bandpass filter. Controllable explosions can be achieved with the help of a special controlled bombing machine.
