摘　　要：自密实高性能混凝土具有高流动性,施工中会对模板产生较高侧向压力。本着降低施工能耗、减少对环境影响、实现节能减排目标,推进自密实混凝土广泛的工程应用,有必要对工程中模板侧向压力进行研究。从自密实混凝土的设计方法、模板侧向压力的影响因素以及模板侧向压力下降机理等进行了分析,为减少自密实混凝土模板侧向压力提供一定的理论基础。Self-consolidating concrete is a kind of high performance concrete with high mobility.Therefore formwork pressure is high.In order to realize the target of energy saving and emission reduction and promote self-consolidating concrete to get more extensive application, it is necessary to make a research for formwork pressure.Design method of self-consolidating concrete, reduction mechanism of formwork pressure, factors of influencing formwork pressure were studied in this article to provide certain theoretical basis of formwork pressure.
