公路涎流冰(冰椎)是高寒地区公路主要病害之一。它是冻土地区特殊的工程地质现象。本文以大兴安岭林业管理局呼中林业局31支线两处公路涎流冰的试验研究为例,阐述了高寒地区公路涎流冰对交通运输的危害及治理意义,并着重讨论了涎流冰的成因和形成条件。文中明确提出人类工程活动对涎流冰形成的重要作用,还提出了治理方案。
Highway saliva ice (ice vertebral) is one of the main road disease in the alpine region. It is a special engineering geological phenomenon in the permafrost region. In this paper, the experimental study of highway saltwater ice in 31 branches of Huanzhong Forestry Bureau of Daxinganling Forestry Bureau was taken as an example to illustrate the harm of highway salty ice in the alpine region and its governance significance. The causes of salivation ice And forming conditions. The article clearly put forward human engineering activities on the formation of ice saliva stream important role, but also put forward the program of governance.
