Detection method for calculating compactness by using elastic modulus

The invention discloses a detection method for calculating the compactness by using an elastic modulus. The detection method comprises the following steps: step S1, partitioning an engineering filling material; s2, verifying the maximum dry density over the years; s3, collecting detection data; s4, establishing a database; and S5, calculating the compaction degree. Compared with the prior art, the method has the advantages that the correlation coefficient database is established through the correlation between the compaction degree of various soil properties and the elastic modulus, the compaction degree is calculated by combining the correlation coefficient with the elastic modulus, the method is suitable for rapid detection of various filling compaction degrees in engineering construction, quality control in the construction process is achieved, the detection efficiency can be improved, and the detection cost is reduced. And particularly, the method has important significance for improving the engineering c
