| 中文摘要: |
| 通过表面振动与振动台两种方法进行粗颗粒混合料最大干密度测试，试验结果表明：同一种土湿土法做出的最大干密度明显要大于干土法所测的最大干密度，表面振动仪法的振密效果要优于振动台法的振密效果。通过高速铁路路基施工现场压实后路基干密度与室内最大干密度测试结果对比，发现既有路基施工工艺可以达到以表面振动法测试得到最大干密度的95%压实度。 |
| 英文摘要: |
| The maximum dry density was tested by the surface vibration machine and vibration table, and it was indicated that the maximum dry density of coarse grained soil mixture which was obtained by wet method was larger than that obtained by dry method. In addition, the surface vibration’s result was better than that from the vibration table. The construction technology could accomplish 95% compaction which was calculated based on the maximum dry density by surface vibration in the high speed railway construction. |
