摘　　要：乌尉高速是G7北京~乌鲁木齐高速公路联络线G0711乌鲁木齐~尉犁~若羌高速公路主要组成部分,为连接天山南北的纵向大通道,全线具有严寒、大温差、四季常风、降水丰富等气候条件。通过对该线路前峡2#隧道在建隧道洞口地表位移方向、速度、累积量和天气情况进行中长期监测,探究降水与隧道洞口地表位移大小、方向之间的密切联系,并初步阐释其机理,以期为严寒大温差地区隧道的高精度监测及相关研究提供参考。Wu-Yu Expressway is the main component of G0711 Urumqi~Yuli~Ruoqiang Expressway,the G7 Beijing~Urumqi Expressway Liaison Line,which is a longitudinal corridor connecting the north and south of Tianshan Mountain,and the whole line has the climatic conditions of severe cold,large temperature difference,four-seasonal winds,and abundant precipitation.Through the medium-and long-term monitoring of the direction,speed,accumulation and weather conditions of the surface displacement at the tunnel opening of the 2#tunnel under construction in the former gorge of the line,the close connection between precipitation and the size and direction of the surface displacement at the tunnel opening is explored,and the mechanism is initially interpreted,with a view to providing references for the high-precision monitoring of the tunnels in the region of severe cold and large temperature difference,as well as the related researches.
