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