摘要
通过应用不同固化剂对加固软土的作用进行室内试验,研究了NO.5固化剂、NO.1固化剂加固粘土的无侧限抗压强度变化的规律。分析和讨论了NO.5固化剂和NO.1固化剂加固土在不同掺入比和龄期时强度的变化规律及应力～应变特性,从整体加固效果分析看出,NO.5固化剂加固土效果优于NO.1固化剂加固土,两种固化土的最佳掺入比在12%～15%,可在软土地基处理和实际工程中应用。
The indoor test of using different curing agents to strengthen soft soil was performed in this paper to study the rules of unconfined compressive strength changes using No.5 and No.1 curing agent.It also studies the intension changing rules and stress characteristics of different mixing ratio of 2 agents in different time.The strengthening results shows that No.5 agent is better than No.1,the best mixing ratio is 12%~15%.It can be used in soft soil foundation treatment and actual engineering.
