| 摘 要： | CTMAB是一种新型的有机阳离子表面活性剂，采用CTMAB对天然膨胀土进行了化学改良试验研究，探讨了其改良机制和改良效果。试验结果表明：经过改良剂改良后的膨胀土与原状土相比，其塑性和膨胀性得到了明显降低，水稳定性有了显著提高，在经过不同次数的反复溶漓后，土样仍具有一定的强度。说明了CTMAB对膨胀土的工程性质有一定的改善作用。该成果已申请获得了国家发明专利。

| Abstract: | CTMAB is a new organic cationic surfactant. A chemical improved experiment is based on CTMAB towards to the natural expansive soil; and the improved mechanism and effect are studied. The result shows that the plasticity and expansibility of stabilized expansive soil decrease significantly compared with plain soil; and its water stability increases obviously. Soil samples remain enough strength after repeated dessolution different times, which indicates that CTMAB can effectly improve the engineering properties of expansive soil. The achievement patent has been authorized. |
