“康耐”处治高液限土路基的试验研究

Test Study of KANGNA Treaded High Liquid Limit Subgrade

结合阳(江)茂(名)高速公路利用高液限土的工程实例,讨论“康耐”土壤稳定剂与高液限土的作用机理,提出“康耐”稳定高液限土路基的试验内容,分析试验路堤采用“康耐”稳定高液限土的物理力学指标。实例证明,使用“康耐”土壤稳定剂是解决高液限土路基难以晾晒和难以压实问题的行之有效的方法。

According to the actual project sample of the Yanmao expressway utiliz ing high liquid limit soil, the role principle of the KANGNA stability agent and high liquid limit soil are discussed, the test content of the KANGNA stabilized high liquid limit soil subgrade are presented, and the physical and mechanical index of the test embankment used KANGNA stabilized high liquid limit soil are analyzed. The actual project have proved that KANGNA stability agent was of effe ctive method which solved high liquid limit soil for the difficult dry in the su n and difficult compaction.
