| 摘 要： | 通过不断改变砾石土中粉粘粒含量,进行击实试验,找出选择不同击实方法的粉粘粒含量分界点。针对不同最大公称粒径Dmax和不同n值的12种级配砾石土进行振动击实和重型击实试验,来获得其最大干密度与级配指数n的关系,找出n值分界点;对于不良级配砾石,进行了如何确定最大干密度和压实度检测方法的研究。 |

| Abstract: | In the experiment,the powder-viscous grain content were changed to test the compaction for finding out the viscous grain content boundary with different compaction methods.Directed against 12 kinds of coarse-grained soil with different nominal maximum diameter Dmax and different value n,through surface vibrated compaction and heavy compaction test methods in the lab,the relationship between the maximum dry density and graded index n is analyzed,and the boundary of n value is found out.For poor graded gravel... |
