In earth-rock filling works，Quality of rolling construction，It has a decisive impact on the safety and life of the structure.。Effective compaction can ensure the bearing capacity of the structure.、Stability and durability，Prevent subsidence。With the scale of construction、Increase in construction intensity，It puts forward higher requirements for the quality control of earthwork filling construction，The traditional manual quality management mechanism can not meet the current requirements of large-scale mechanized construction and construction schedule.。

At present, hydropower construction in China，The compaction construction of earth-rock dam mainly adopts double control：Process control and final parameter control，However, the subjectivity of process control is relatively strong at present.，It mainly depends on the work experience of the operator.，Spot inspection is adopted for final parameter control.，Long existence detection period，The results can not truly reflect the reality of the compaction quality of the warehouse surface.。

So，The School of Surveying and Mapping of Wuhan University has studied a kind of continuity.、Real-time、High precision、Automation、Quality monitoring system for earth-rock filling and rolling construction with the characteristics of intelligence and the like，Real-time monitoring of filling and rolling construction process，And timely feedback to the construction personnel for control and adjustment，So that the filling and rolling construction quality is always in a truly controlled state.，This is of great practical significance to the construction quality of earth-rock filling project。
