摘要
利用自制重球震源,对比试验了不同重球高度、不同重球重量激发出的有效波振幅及频率的关系,通过对试验资料的分析得出,重球震源激发的有效波的振幅随激发能量的增加而增大,但有效波振幅的增加幅度随激发能量的增加逐渐趋缓,激发的地震波主频和工程地质条件有关,不同的激发能量对地震波主频基本上没有影响。
By the use of self made heavy ball source, contrasted relation between effective wave amplitude and frequency shot by different heavy ball heights and weights. From testing data analysis, the effective wave amplitude of heavy ball source increasing along with shot energy, but effective wave amplitude increased extent is gradually tend to become slower along with the increase of shot energy. The seismic wave dominant frequency is related to engineering geological conditions, different shot energy is basically no impact to seismic wave dominant frequency.
