Vibratory parameters and vibratory compacting mechanism of eolian sand

Through the test of the biggest density by the vibration table in different vibratory-frequency, wing, vibratory-time, compacting-weight, water-content and filling-manner, the rules and the degree that these vibratory parameters influence the vibratory compacting of the eolian sand is studied. Then based on the orthogonal test of the main parameters, this paper analyzes the influencing primary and secondary by the vibratory parameters, and the optimum combination of the parameters is confirmed. Based on the laboratory tests, the vibratory compacting mechanism of eolian sand is analyzed by dynamic mechanics method. The research indicates that the best vibration frequency is 45~50 Hz in dry and the best moisture content state, and it is better to use high frequency (45~50 Hz) and small amplitude (0.4~1.0 mm) when the eolian sand is compacted.
