摘　　要：结合工程实例,介绍球冠形采光顶钢结构斜坡轨道整体滑移施工重点技术,包含钢结构拼装,斜坡轨道布设,跨越圆形采光井段的轨道加固支撑,钢结构整体滑移、顶升及降落等工艺。斜坡轨道上钢结构的整体滑移施工经验,对施工操作区间有限、滑轨跨越大型孔洞的工程具有一定的借鉴作用。Combined with the engineering example,this paper introduces the key construction technologies of integral sliding of steel structure slope track of spherical crown lighting roof,including steel structure assembly,slope track layout,track reinforcement support across the circular lighting shaft section,integral sliding,jacking and landing of steel structure.The experience of integral sliding construction of steel structure on slope track has a certain reference for the projects with limited construction operation area and sliding track crossing large openings.

关 键 词：球冠形采光顶 钢结构 斜坡轨道 整体滑移
