摘　　要：在西北高寒地区钢筋混凝土井塔施工中,通过对桩基范围人工冻土的快速解冻技术和高寒地区冬期井塔快速施工成套技术的研究应用,确保了工程质量,加快了井塔桩基和冬期井塔主体的施工速度,缩短了井塔施工工期,解决了高寒地区煤矿建设周期长的施工技术瓶颈问题。During the reinforced concrete headframe construction in alpine areas in Northwest China,by the research and application of rapid thawing technology in pile foundation range and rapid headframe construction technology in winter,the project quality can be ensured;the construction speed of headframe pile foundation and headframe body in winter was accelerated;the time of headframe construction was shortened and the bottleneck problems of coal mine construction in alpine areas were solved.

关 键 词：西北高寒地区 钢筋混凝土井塔 人工冻融土 快速解冻 冬期 井塔冬期快速施工成套技术
