摘　　要：沥青路面冬期施工环境温度低,施工技术难度大。文章以大连湾海底隧道沥青路面施工为例,详细介绍了沉管隧道沥青路面冬期施工方法、保温措施、有限空间安全环保措施等。沉管隧道路面冬期施工的成功,积累了施工经验和参数,可为类似隧道冬期低温条件下沥青铺设工程提供参考。The winter construction environment temperature of asphalt pavement is low,and the construction technology is difficult.Taking the construction of asphalt pavement in Dalian Bay immersed tunnel as an example,this paper introduces in detailed the winter construction methods,insulation measures,and limited space safety and environmental protection measures for asphalt pavement in immersed tunnels.The successful winter construction of immersed tunnel asphalt pavement has accumulated construction experience and parameters,which can provide reference for asphalt laying projects under low temperature conditions in similar tunnels during winter.

关 键 词：冬期施工 沥青铺设 保温措施 有限空间
