摘　　要：通过对膨胀土掺和石灰-煤粉灰进行改性试验,研究了汉中膨胀土改性前后胀缩性、强度等性能的变化,得到了膨胀土掺和石灰-粉煤灰进行改良的最佳掺量为质量分数石灰8%,粉煤灰16%,将为汉中膨胀土治理提供参考。Through the experimental research on amelioration of expansive soil with mixing in clime-flyash, the characteristics of expansive and shrinkage and the changes of compressive strength are analyzed to get the optimal ratio of adding in clime-flyash for amelioration of expansive soil. The result show that the optimal ratio of adding in clime and flyash is 8% and 5%. which can provide the reference for treatment of expansive soil roadbed.
