摘　　要：通过钢筋位移混凝土保护层厚度的变化对混凝土受弯构件结构性能的影响进行定量分析结果表明,钢筋位移保护层厚度过大是造成混凝土结构性能的承载力下降、裂缝宽度超标、挠度超限的重要原因.从而导致混凝土结构存在安全隐患,影响工程结构的安全性、适用性和耐久性.This article carries on the quantitative analysis result through the steel bar displacement concrete protector thicknes change to the concrete structure performance influence which indicate. The important reason which creates the concrete structure performance supporting capacity drops, crack depth exceeds the allowed figure, flection ultra limits is that the steel bar displacement protector thickness oversized. Thus it causes hidden danger on the concrete structure which affects the project structure security, the service ability and the durability so on.
