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 ,提出了风积砂路基回弹模量建议值
The effect of different compaction degrees and different water contents on the sand-based resilience modulus was studied through a large-scale test tank trial of aeolian sand embankment. It was found that there was a good correlation between the modulus of elasticity and the degree of compaction Cubic polynomial relationship, but little affected by the water; through a large number of tests and analysis, put forward aeolian sand subgrade modulus of recommendation
