Freezing Damage Prevention Technics of Retaining Wall in Seasonal Frozen Soil Region

Based on the studies of the frozen soil mechanics and the frozen soil physics in the recent years,the main content of the prevention technics of the retaining wall in the seasonal frozen region are briefly introduced. They may be references for the engineers because the contents widely include freezing damage forms , the reasons of the freezing damage , calculation methods of the prevention structures and the design parameters determination of resisting the frost heaving of the retaining wall.
