This paper introduces

analyses and appraises the principle and operating rule of newly and existing earth—filled compaction checking technology. Based on making penetrating analysis

this paper expounds the necessity

mechanical model

the accomplishing ways and newly international preparing advance of developing compaction machine assembling system. The basic principle and working properties of compaction machine assembling system are also described; and that for satisfying basic needs of earth-fill compaction quality in civil engineering (such as quantity of settlement

rate of settlement and so on) the mechanical intensity (such as K30

dynamic rigidity coefficient and so on) should be taken for standard of reference in preparing compaction machine assembling system.
