Construction of environmental vibration prediction model for subway transportation based on machine learning algorithm and database technology.

In the measurement of different depths of the soil layer, the change of the measured value of different depths of the soil layer shows a tendency of rising and then falling, according to the curve change, it can be found that the peak value of acceleration gradually decreases after the depth of the ground increases, which indicates that the amplitude of the additive number shows a decreasing trend when the overall depth increases, which may be caused by the vibration propagation being affected.
