摘要
为研究不同含泥量风积沙的压实特性，确定适合路基填料的风积沙，采取风积沙试样，制备7种不同含泥量的风积沙，运用重型击实法、干振法和水振法进行试验．试验结果表明，含泥量在8％以下的风积沙适合用水振法确定最大干密度，含泥量在8％以上的风积沙适合用重型击实法确定最大干密度，干振法确定最大干密度效果最差．含泥量为16．5％～30．2％风积沙的干密度接近最大值，压实特性最好，适合作为路基填料。
In order to study compaction characteristic of aeolian sand of different mud, and get suitable aeolian sand of different mud that is used subgrade filling, seven aeolian sand of different mud is made by taking representative sample of aeolian sand. Some tests of heavy compaction method, dry vibration method and water vibration method are done. The results show that the aeolian sand of the mud below 8% is suitable of using water vibration method to determine maximum dry density, and the aeolian sand of the mud of greater than 8% is suitable of using heavy compaction method to determine the maximum dry density. Dry vibration method to determine maximum dry density is the worst effect. The aeolian sand of the mud 16.5% - 30.2% is suitable for subgrade filling, because of the close maximum dry density and the best compaction.
