| 摘 要： | 采用室内无侧限抗压强度试验，证明了矿渣硅酸盐水泥和普通硅酸盐水泥在加固滨海软土的效果方面存在较大的差异。通过X射线衍射分析，对两种水泥加固软土效果差异的内在机制和原因进行了探讨。结果显示，水泥土的强度与水泥水化产物的生成量之间存在一致性，矿渣水泥加固土可生成更多的水化产物，并能够限制软土中可溶盐对水泥土的影响。

| Abstract: | The unconfined compression test is utilized to research on the cemented marine soft clay and testifies that there is considerable discrepancy between the effect improved by slag cement and that by Portland cement. X-ray diffraction analysis is employed to investigate the mechanism and the causes of the discrepancy. It is observed that the strength of the cemented soil is related to the amount of the cement hydrates. Slag cement generates more hydrates, and restricts the influence of soluble salt in the soft clay on cemented soil. |
