振动压路机通过连续高速冲击地面施加压力达到压实土壤的目的。振动使土颗粒向其它颗粒之间的空隙移动 ,使土颗粒达到最紧密排列。如果土是干燥的 ,磨擦力会阻碍颗粒移动 ;如果土的含水量过多 (水是不可压缩的 ) ,它会占据颗粒间的空隙。正确的含水量能润滑土颗粒 ,使之移动时 Vibratory roller to achieve the purpose of compaction of the soil by applying pressure on the ground at a continuous high speed impact. Vibrations move the soil particles toward the interstices between the other particles, resulting in the closest arrangement of the soil particles. If the soil is dry, the friction will hinder the movement of the particles; if the soil has too much water (the water is incompressible), it will take up the space between the particles. The correct moisture content can lubricate the soil particles when they move
