摘　　要：工程冻害问题,在我国寒冷和较寒冷地区普遍存在,对工程的危害性是相当大的。寒冷地区工程冻害虽非突发性灾害,但在冬季短暂的一到三个月内就会产生,并且危及各类工程正常运行,从而造成重大的经济损失。明确造成工程冻害问题的主要原因,并采取相应措施防止工程冻害现象的发生,对寒区工程冻害问题的防治具有十分重要的意义。通过调查相关文献资料以及户外实地考察相结合的方式,对寒冷地区常见的道路、房建、水利工程冻害的形成原因、特点进行调查,并对相应的防治措施进行分析。The problem of freezing damage to the project is widespread in cold and cold regions of China,and the hazard to the project is considerable.Although freezing damage in cold regions is not a sudden disaster,it will occur within a short period of one to three months in winter,and it will endanger the normal operation of pipelines and other projects,resulting in major economic problems loss.Therefore,the main cause of the freezing problem of the project is clearly identified,and corresponding measures are taken to prevent the occurrence of freezing damage to the project,which is of great significance for the prevention and control of the freezing damage in the cold region.Through the combination of investigation of relevant literature and outdoor field investigation,this paper investigates the causes and characteristics of freezing injury of common roads,housing construction and water conservancy projects in cold areas,and analyzes the corresponding prevention and control measures.
