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。
Through direct shear test, the law of gangue＇s sheafing strength changing with compactness and when the compactness is 95 %, the law of gangue clay mixture＇s sheafing 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.
