一、引言在地震勘探中主要使用的震源有二种,一种是爆炸源,另一种是可控震源。利用爆炸源存在一次性激发不能重复记录、有污染、有危险等许多不可克眼的实际困难。而利用可控震源可多次激发重复记录、经济安全、并且随着GPS等高新技术的采用,可控震源将得到越来越广泛的应用。二、力的传输分析可控震源的振动器底座安置在地面上,如图所示,如在惯性质量mi上的振荡力F_0(t)下,是直接 I. INTRODUCTION There are two main sources of seismic exploration, one is the source of the explosion, and the other is the vibrator. The use of explosive sources exist one-time excitation can not be repeated records, there are pollution, there are many dangerous and so can not be guessing the actual difficulties. The use of vibrator can repeatedly stimulate repeated records, economic security, and with the introduction of GPS and other high-tech, vibrator will be more and more widely used. Second, the force transmission analysis Vibrator base vibrator placed on the ground, as shown, as in the inertial mass mi oscillation force F_0 (t) is directly
