| 摘 要： | 通过无侧限抗压强度试验对比分析了有机质含量、水泥和石膏掺量对水泥固化土和XGL2005固化土强度形成规律的影响。分析结果表明，XGL2005固化土的强度均不同程度地高于水泥固化土的强度，而且强度增长也快于水泥固化土。结合抗压强度试验和扫描电镜试验分析了固化土微观结构变化和强度发展之间的对应关系。

| Abstract: | Unconfined compressive strength tests have been done to analyze the influence of the content of organic matter, cement and gypsum on the strength development of cement stabilized soil and XGL2005 stabilized soil respectively. The results indicated that the strength of XGL2005 stabilized soil is higher than that of cement stabilized soil; and the strength increasing ratio of the latter is larger than the former. Combining the strength tests and the SEM tests, study had been done on the corresponding relationship between the strength development and the microstructure variation of XGL2005 stabilized soil. |
