针对高寒地区修建隧道面临的冻害问题,通过冻害发生影响因素及冻害发生机理分析,结合隧道防排水方案及冻胀力对结构影响的研究,了解隧道病害的成因,并提出处理方法及防治措施。
In view of the frost damage problems faced by tunnels in alpine regions, the causes of frost damage and the mechanism of frost damage were analyzed. Based on the study of the influence of frost heave forces and the scheme of drainage and drainage on tunnels, the causes of tunnel diseases were analyzed and the treatment methods and prevention measures were proposed.
