| 摘 要： | 不同固化剂对软土的加固效果有一定差异，且固化土的强度特性愈来愈受到重视。通过不同掺入比和不同龄期时固化土（新型固化剂#Ι）的无侧限抗压强度试验结果，分析了掺入比、龄期对固化土强度的影响。试验结果表明，固化剂#1对黏土的加固效果优于水泥，固化土的强度为水泥土的1.5～2.4倍；固化剂强度与龄期、掺入比关系密切，不同掺入比时随龄期的增长固化土强度的变化也有所不同。

| Abstract: | With the application of new solidifying agent to ground engineering, the influence of solidifying agent on the strength of solidified clay is widely noticed. The variation of unconfined compressive strength of the clay improved with solidifying agent ^#I with different mixing ratios and ages are studied through the laboratory experiment. The data of unconfined compressive strength show that the stabilizing effect of the agent ^#I Iis superior to that of cement.A prediction equation is developed for calculating the strength of stabilized clay by analyzing the experimental data. |
