摘要
通过风积砂路基大型试槽试验 ,研究了不同压实度、不同含水量对砂基回弹模量的影响 ,发现风积砂路基的回弹模量与压实度有相关性很好的三次多项式关系 ,而受水的影响极小 ;通过大量试验分析 。
The effect of different compaction degree and moisture content on the resilience modulus of aeolian sand subgrade by large scale test model is studied in this paper It is pointed that the resilience modulus has very close triple equation correlation with the compaction degree and has little to do with the moisture content The suggested value of resilience modulus for aeolian sand subgrade is indicated through a lot of tests and analysis
