| 摘 要： | 采用高性能固结材料(HPCM)对原状土进行改良,对改良土体的加州承载比(CBR)、压实度和吸水膨胀等性能进行了试验研究、SEM(扫描电镜)和XRD(X-射线衍射)分析.结果表明,改良土体的CBR值和耐水性显著提高.与传统固结土体方式不同,HPCM是通过物理化学交互作用使土颗粒的粘结性增强,使土体形成紧密聚积的结构,从而显著改善压实土体的稳定性. |
| 关 键 词： | 高性能固结材料 加州承载比 稳定性 耐水性 |

| Abstract: | To enhance the stability of soil filled in the roadbed of expressway,a high performance consolidating material(HPCM) was used to improve the stability of primary soil,and its performances such as CBR(California bearing ratio) value,compactness and expansion were investigated through a physical test,SEM(scanning electron microscopy) and XRD(X-ray diffraction) analyses.The research result shows that the CBR value of soil treated by HPCM is increased.Different from conventional approaches to stabilize roadbed,the mechanism of HPCM is to form a tight structure by increasing the combination of soil grains through the interaction of physical and chemical effects to enhance the stability of treated soil. |
| Keywords: | high performance consolidating material California bearing ratio stability water resistance |
