| 摘 要： | 通过直剪试验，得到了煤矸石抗剪强度随压实度变化的规律以及在压实度为95 %时的煤矸石与粘土混合料的抗剪强度随煤矸石含量变化的规律，提出了混合料中煤矸石含量为50 %~60 %时可取得较好的抗剪效果，可在路基工程中应用。

| Abstract: | Through direct shear test，the law of gangue’s shearing strength changing with compactness and when the compactness is 95 %，the law of gangue clay mixture’s shearing strength changing with the content of gangue could be obtained.It is suggested that when the gangue content in the mixture is 50 %~60 %，shearing resistance effect is good and its application in subgrade engineering is feasible. |

| Keywords: | gangue mixture direct shear test shearing strength |
