涎流冰在我国季冻区的公路建设中经常遇到,若处理不当,其危害性相当大。结合吉林至延吉高速公路敦化至延吉段涎流冰形成的类型、特点和规模,对涎流冰的形成机理做了研究与分析,按其成因分为沟谷涎流冰和山坡涎流冰。针对吉延高速涎流冰的特点,有针对性地采取了排、挡、积、截等4种措施进行了综合治理,通车运营,3年来未再发生过涎流冰,取得了较好的效果。所以只有以预防为主,防治结合,多方面重视涎流冰,涎流冰的发生才能得到有效控制。

Salivary flow ice is often mat in seasonal frost area in our country.If it is not handled properly,its hazards are quite tremendous.Combining with the types,characteristics and scales of salivary flow ice in Dunhua to Yanji section of Jilin to Yanji highway,this paper makes a study and analysis to the formation mechanism,and according to its causes divides the salivary flow ice into valleys and slopes salivary flow ice.Aiming at the salivary flow ice characteristics in Ji-Yan highway,we adopt four measures of row,block,product and cut in target for the integrated management.Since opening to traffic operation for three years,it has not happened salivary flow ice,and achieved good results.Only sticking to the prevention principle,and by the combination of prevention treatment,paying more attention to various aspects,the occurrence of salivary flow ice can be controlled effectively.
