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

根据近年来冻土力学、冻土物理学等研究成果,简述了季节冻土区挡土墙构筑物冻害防治技术的主内容,包括:挡土墙冻胀破坏的形式,挡土墙冻害产生的原因,挡土墙抗冻结构计算方法,抗冻胀设计参数的确定,挡土墙抗冻技术措施等,可供工程设计人员参考。

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.
