AI Technical Summary
Existing methods for testing the compaction quality of filling projects suffer from poor accuracy and high data dispersion, failing to directly reflect changes in the energy absorbed by the soil during compression.
A detection method based on semi-ellipsoidal compaction work is adopted. By calculating the vertical vibration signal when the vibrating wheel interacts with the soil, the effective compaction work per unit semi-ellipsoid is calculated. Combined with the spatial position signal of the roller, a distribution map of compaction degree or relative density index is generated, and the compaction quality is displayed in real time.
It achieves high-precision, low-discretion, real-time continuous compaction quality detection, which can reflect the changes in soil compression energy and is suitable for various filling engineering scenarios.
