【 摘 要 】

With the needs of engineering construction, non-cohesive soil has been widely used in important fields such as dams and roadbed filling. The strength and compressibility of non-cohesive soil mainly depend on the compactness.However, it has so far been difficult to find a method for determining the compactness of non-cohesive soil quickly, accurately and safely.In order to cope with this problem, this paper focuses on the working principle and operation process of the SDG200 soil densitometer.At the same time, on the basis of summarizing the previous research, it is pointed out that the difference between the operation of clay soil and non-cohesive soil density is tested by SDG soil densitometer, and the parameter setting problem in the non-cohesive soil compactness test is solved.Therefore, it can be predicted that the SDG soil densitometer will have a good application prospect in the detection of non-cohesive soil compactness.
