摘　　要：在地铁明挖区间穿越地震断裂带特殊变形缝施工过程中,区间防水性差,导致地铁明挖区间特殊变形缝部位渗漏情况严重,为此,文中进行了地铁明挖区间穿越地震断裂带特殊变形缝施工技术研究。文中基于太原地铁1号线工程项目施工实例,介绍了明挖区间穿越活动地震断裂带采用特殊变形缝的施工技术,着重阐述了特殊变形缝的施工方法。经检验证明,文中采用的地铁明挖区间穿越地震断裂带特殊变形缝施工技术防水效果好,可以达到预期要求,可为类似工程提供参考经验。In the process of construction of special deformation joint crossing earthquake fault zone in subway open-cut section,due to poor water resistance,the leakage of special deformation joint in subway open-cut section is serious.Therefore,the construction technology of special deformation joint crossing earthquake fault zone in subway open-cut section is studied.Based on the construction example of Taiyuan Metro Line 1,this paper introduces the construction technology of special deformation joint across active earthquake fault zone in open-cut section,and emphatically expounds the construction method of special deformation joint.It has been proved that the waterproofing effect of the special deformation joint across the seismic fault zone in the open-cut section adopted in this paper is good,and can meet the expected requirements,and can provide reference for similar projects.
