The Mechanical Damage of Pavement Structure in the Humidification Deformation of Expansive Soil Roadbed

摘要

A large amount of deformation which caused by expansive soil with water, bring about the highway diseases of expansive soil area. The theory of temperature stress field is applied to analyze the deformation of expansive soil embankment induced by uneven increased humidity, and based on temperature stress field theory, to analyze the mechanical response of pavement, and get the additional stress of pavement, in order to achieve the analysis of pavement damage of expansive soil area under raining.
