Abstract:
Based on analyzing the relationship between the subgrade rebound deflection and soil features, compaction degree, moisture content and so on, this paper studied the interrelationship between moisture content and the subgrade deflection, and found a method to define the seasonal influence of subgrade deflection as consistency correlation. It put forward a new method to determine the subgrade deflection criterion value, which studies for any time. The results indicated that: the different season subgrade deflection and moisture content is power exponent relation; but the relationship between indoor subgrade deflection and consistency is linear; the method of consistency correlation that determines the subgrade deflection value is closer to engineering practice. 5 tabs, 1 fig, 14 refs.
