The geotechnical material parameters of subgrade are achieved from laboratory test results.
In the course of simulation calculation, the impact of different factors on the effect of dynamic compaction is analyzed by way of change the hammer fall-height, impact area, impact times, impact space, and geotechnical material parameters in model.
Table 1 Material mechanical parameters of subgrade soil bulk density (kN/m3) poisson ratio modulus of elasticity (MPa) cohesion (kN) internal friction angle (°) 20.0 0.40 30.0 30 25 The results show that: With the increase of tamping energy, the settlement value and lateral deformation of subgrade increased, and the range of plastic zone also increased substantially; however, with the fall-height of hammer increases, the deformation increment gradually decreased.

The damping material was adopted to reduce the noise of panels in order to reduce the noise of the field.
The front and rear roof panels, front panel, left front panel and right front panel were chosen for placement of the 2mm damping materials layers (the density 1.05kg/m3, elastic modulus 0.3Gpa).
Considering the damping properties of damping materials, the sound absorption performance will not be considered.
The damping materials will also change the frequency distribution of the sound pressure level when reducing noise.
