| 千枚巖棄渣用作路基填料的水穩(wěn)定性試驗研究(51 卷) |
| 英文標(biāo)題 |
| Experimental study on water stability of subgrade filling material utilising phyllite waste muck |
| 摘要 |
| 研究了蘭渝鐵路清水隧道穿越的千枚巖的物理化學(xué)性質(zhì)、擊實特性、擊實試樣的耐崩解性。指出該種千枚巖應(yīng)屬于泥質(zhì)變質(zhì)巖類，擊實后的試樣具有較好的級配，但顆粒明顯變細(xì)；雖然擊實樣的膨脹性較弱，但耐崩解性差，崩解速度較快。綜合判斷該種千枚巖棄渣不宜直接作為鐵路路基填 |
