摘要
Abstract
In China's seasonal frozen soil region,frostheaving,a tough problem encountered by concrete lining canal,is widely distributed and does great harm to water conveyance project.To explore its damage mechanism and control measures is of great importance.Through the site test on polyurethane thermal insulation plate in the south canal of Lin-he,Inner Mongolia,this paper explores the changing rules and features of the ground temperature,frozen depth,moisture content and frost heave amount with treatments of boards of different thickness,with the anti-freeze expansion plan for the concrete lining channel in this region.The results showed that polyurethane thermal insulation plate could effectively reduce the frost heave damage to rigid lining material of canal,ensure the stability of lining and the safety of canal,which will be of value for the selection of thickness of insulation materials in the rigid lining canal.关键词
