摘　　要：钢纤维混凝土凭借其中钢纤维有效地传送与分配应力,提高混凝土的抗拉强度、抗冲击性以及抗疲劳强度和弹性变形能力,同时性价比高于传统超平地坪,但也有特殊的工艺及难点。在普菲斯项目超平固定地坪施工实践中使用可调钢模板、单侧支模对称浇筑法、超强磁铁滚筒、嵌入式金属铠装缝、高平刮平尺等工艺改进措施很好地解决了施工中的难点,对同类型地面的施工具有指导性作用。Steel fiber reinforced concrete can improve the tensile strength, impact resistance, fatigue strength and elastic deformation ability of the concrete based on the effective transmission and distribution stress of steel fiber, at the same time, the cost performance is higher than the traditional super flat floor, but it also has special technology and difficulties. During the Pfis super flat fixed floor construction project, we use adjustable steel form work, unilateral support symmetrical pouring method,super magnet roller, embedded metal amour seam, high flat scrape ruler to solve the difficulties, they have a guiding role in the construction of the same type of the same floor construction.
