In order to improve the quality of the project, we adopt the intelligent compaction\ncontrol system and collect CMV values through experiments. In the\nexperiment using finite element simulation software to simulate and analyze.\nFrom the simulation results to analyze the road surface displacement and\nstress trends, derived from the displacement of the pressed material in the\nfifth pass, the sixth pass is almost the same, the rate of change close to 0, can\nbe considered pressed material has the desired pressure. The actual degree is\nin good agreement with the actual compaction of sand filling, indicating that\nthe compaction state of the pressed material can also be verified from the\nstress angle of the pressed material. The stress change from the weak vibration\nto the strong vibration load increases first and then decreases rapidly, and the\nreduction of strong vibration is more obvious. Therefore, the simulation result\nalso shows that the strong vibration has the better compaction effect than the\nweak vibration.
