| 摘 要： | 采用水泥、粉煤灰对闽江口地区的软粘土进行改良加固试验 ,测试不同水泥及粉煤灰掺入质量比、不同龄期的加固软粘土的抗压强度 ,并运用扫描电子显微镜 (SEM )对加固土的微观结构特征进行观察分析 .研究结果表明 ,当水泥掺入质量比为 16 % ,粉煤灰掺入量为水泥质量的 4 0 %时 ,加固土的强度最大 ,并且强度随着软粘土含水量的增加而降低 ,随着水泥掺入比、养护龄期的增长 ,水泥土及水泥 -粉煤灰加固土的抗压强度也随之增加 .

| Abstract: | Soft soil in the Minjiang estuary was reinforced by using cement and fly-ash.Compression strength of stabilized clay with different mixing amount of cement and fly-ash is tested at different curing ages.The microstructures of stabilized clay samples are studied by means of scanning electron microscope (SEM).The results show that the intensity of stabilized soil is the largest by using the stabilizer composed of 16% cement mixing ratio and 40% fly ash mixing amount,and it is reduced with the growth of the water content of soft soil and is increased with the growth of the cement mixing ratio and curing age. |
