| 摘 要： | 通过加荷固结稳定后的冻胀试验，分析了上覆荷载对冻胀的影响，得出冻胀与法向冻胀力的产生是相辅相成的，最后，将低液限黏土的法向冻胀力的分级标准与现有规范对比，得出各冻胀性类别的法向冻胀力界限值基本相同。

| Abstract: | Based on the frozen-heave test under load after consolidation,the effect of load over on frozen-heave is analyzed and it is concluded that frozen-heave and normal frozen-heave force supplement each other,lastly,by comparing the classification standard of the normal frozen-heave force of low liquid-limit clay with present criterion,it is concluded that the limit values of all kinds of normal frozen-heave forces are almost the same. |

| Keywords: | low liquid-limit clay pre-increasing load normal frozen-heave force frozen-heave ratio water content |
