隧道建成后渗漏水与冰冻是严寒地区公路隧道的顽症，长期以来一直困扰着我国北方寒冷地区公路隧道的运营，吉林省长春至珲春高速公路新交洞隧道的施工中采用了“堵水、防水、排水、保温、供热”等多项新技术对其进行综合防范，防水效果良好，可为今后类似寒区隧道防排水与保温防冻提供借鉴。

Water leakage and freezing are difficult problems of completed highway tunnels in frigid areas, which bring perplexity to the operation of highway tunnels in frigid areas in northern China. During the construction of Xinjiaodong tunnel on Changchun～Huichun highway in Jilin province, many new technologies such as “water interception, waterproofing, drainage, heat preservation and heat supply” are adopted to avoid such problems and satisfactory waterproofing effects have been achieved. The article can provide reference for the waterproofing, drainage, heat preservation and antifreezing of similar tunnels in frigid areas in the future.
