Roadbed dynamic compaction reinforcement effect evaluation method
The invention provides a roadbed dynamic compaction reinforcement effect evaluation method which comprises the following steps: (S1) leveling a test point position; (S2) testing a roadbed dynamic modulus EPi of the test point position; (S3) performing dynamic compaction; (S4) leveling a dynamic compaction point position, and testing a roadbed dynamic modulus EPi+1 of the dynamic compaction point position; (S5) calculating a dynamic modulus ratio N=EPi+1/EPi, wherein if N is less than or equal to 1.05, the dynamic compaction operation is ended; if N is greater than 1.05, the steps (S3) (S4) and (S5) are repeated until N is less than or equal to 1.05. The invention aims to provide the roadbed dynamic compaction reinforcement effect evaluation method which is easy and convenient to apply, higher in efficiency and lower in cost.
