低路堤应力场水分场耦合模型研究

Reach of the Coupling Model With the Stress and Moisture Field

本文结合对辉乌高速长春至农安段现场土样分析,讨论了应力场水分场双场耦合对低路堤强度的影响,建立了双场耦合模型.通过模拟和分析得出低路堤在双场耦合下总应力的瞬态变化,以及路基纵向位移、横向位移的规律.

Analysis based on the soil of project with Hunwu highway from Changchun to Nongan in china, the cou- pling model of the stress and moisture field is established. The simulation and measured date indicate that how to change about total stress with low embankment under coupling model, in conclusion we can find out the law with longitudinal displacement and lateral displacement.
