摘要:
采用工业副产品木质素对粉土进行改良,探讨了干湿循环作用下素土以及3%木质素改良土的粘聚力,内摩擦角和抗剪强度的变化规律.试验结果表明:木质素掺入后土体的粘聚力、内摩擦角和抗剪强度均有所下降,但经过若干次干湿循环后,木质素改良土粘聚力和抗剪强度明显高于素土,表现出良好的水稳定性.
Abstract:
The lignin of industrial by-product was used to improve soil,and the changes of cohesion,internal friction angle,and shear strength of plain soil and 3% soil improved by lignin under wetting-drying cycles were discussed.The results showed that the cohesion,internal friction angle,and shear strength of the soil decreased after lignin was incorporated,but after several wetting-drying cycles,the cohesion and shear strength of the soil improved by lignin were significantly higher than pure soil,it showed good water stability.
