Subgrade soil compactness is an important technical index to measure subgrade strength and evaluate its bearing capacity,and it also is a controlling difficulty during making subgrade model for laboratory experiment.Through scheme design and data analysis of the experiment,this paper studies the change law of subgrade soil compactness according to hammering times and dropping height.Based on that,it determines reasonable control method of subgrade soil compactness in laboratory experiment and verifies the practicability and effectiveness of the method experimentally.
