Summary
Vibroseis has become the most widely used method in land data acquisition. When the vibrator baseplate is coupled with the ground, the ground seen by the baseplate is captured and becomes a part of source. Many researchers have developed methods to estimate this captured ground mass system. However, no one gives a quantified geometry of this captured ground mass system. This paper provides a theoretical study using a finite element analysis model to quantify this captured ground mass system. Meanwhile, through the finite element analysis model, the ground roll is visualized.
