Research On Frost Boiling Model Of The Road In Changchun City

The transportation is the artery of the national economy, along with the development of the urban population and the economy, the transportation system has become the important controls parameter of the national economic development. The frost boiling on the road has been perplexing the safe and unimpeded road in the area of seasonal frozen region, become the important controls parameter of the national economic development. In the area of seasonal frozen region, the road takes place the cycle of freezing and thawing variety with the season, the mainly disease harm generating from this is the frost heave and frost boiling etc...The disease harm belongs to the heat transfer problem, but the effective measure to prevent and cure the frost boiling has something to do with the gradient of temperature and humidity. Making clear the condition of the temperature, humidity and stress in structure system of the road surface, that is the condition precedent to accurately design the road foundation and the road surface, and prevent and cure the frost heave and frost boiling. Currently, there is no good theory interpretation managing the road frost boiling, so studying on this is very meaningful. This text mainly studies the road frost heave frost boiling breakage reason, and establish model, and simulate the breakage form. Provide science, reasonable and economies, practical theory reference for the construction and repair of the urban road.First, introduce the purpose, meaning and the research actuality of the research on the frost boiling road. Then abstract and analyze the growth environment of the frost boiling road in Changchun City.Secondly, this text has a comprehensive study on the reason of the frost boiling of frost heaving and boiling at chapter 3. The first chapter analyzes the process of frost heaving and boiling, and then put forward the grade division for the harmfulness of frost boiling of roads. Paper gives the influencing factors of frost heaving and boiling systematically. It means that influence...
