| 摘 要： | 吉林省按照公路自然区划隶属于季节性冰冻地区，公路路基面临着±30qC的温度变化．冬季，路基在低温、土质及湿度耦合作用下，容易产生冻胀现象；而春季升温时，由于高温、土质及温度的耦合作用，使路基易产生翻浆现象。我国现行半刚性基层沥青路面的设计规范中，给出16种特殊路基的处理方法，但不包括季冻区路基。本文在大量调查季冻区公路路基病的基础上，提出了对季冻区路基设计补充控制指标的思想．采用这一思路进行季冻区公路设计，则对于路基病害有很强的针对性． |

| Abstract: | According to the area division of highway natural conditions, Jilin province is in the II 2, that is, seasonal frozen area. The highways in this area are facing extreme temperature. Under the low temperature, heave will devel- op, and when the temperature rises, the melting soil will cause the embankment soft. In the specification, many spe- cial embankments of highway were given special methods to deal with, except that of seasonal frozen area. On the basis of the disease investigation, the supplementary indexes were proposed, and this will make the design of pave- ment structure more acceptable. |
| Keywords: | embankment of seasonal frozen area frost heave frost boiling heave diseases pavement design |
