Base on the analyses of the destroyed types and mechanisms of the National Highway 213 from Hezuo to Langmusi, which lies in a seasonal frozen soil region, the engineering techniques for solving frost heaving and frost boiling of embankment in the rebuild engineering are proposed. The average altitude of the highway is about {2 950 }~ {3 620 } m a.s.l. Meteorological data show that the maximal frozen depth in this area is 1 ^42 m. There is a large amount of soft soil, such as humus soil and black land along the highway, as well as swamp, which damage the way construction and operation. The original way had suffered heavy damages from cold weather and bad engineering geological conditions. In the rebuilding engineering of the highway 213 from Hezuo to Langmusi, designers adopted some engineering techniques in accordance with the engineering conditions of different sections of the way. Replace-filling embankment with gravel and riprap for extruding silt are built. Geotextile is also used to strengthen the embankment and obstruct moisture into the embankment. Practice shows that the engineering techniques are effective in preventing frost heaving and frost boiling of embankment. These techniques are also applicable to the areas of similar condition.

在分析国道213线合作郎木寺段原有公路病害类型及机理基础上,总结和研究了改建工程中该路段不良路基的处理技术.季节性冻结、腐殖土、黑土及沼泽湿地是合作-郎木寺路段改造工程中遇到的主要工程问题,根据不同路段具体的工程地点特征,采用了砂砾换填、抛石挤淤、铺设土工布等相应工程措施.近2a的实践证明,这些措施不仅对于防治道路冻胀、翻浆和路基沉降病害是有效的,而且对类似地区道路工程建设具有重要借鉴意义.
