Abstract
A method for determining a performance of a subgrade of an expressway section and a processing device thereof are used to accurately calculate a stress, a displacement, a velocity and an acceleration at any position inside the subgrade while analyzing the performance of the subgrade of the target expressway section, in full consideration of the moving speed and vibration characteristics of the vehicle load, the layered characteristics of the expressway and the unsaturated characteristics of the subgrade soil.
