摘　　要：钢管混凝土柱成为房屋建筑中的重要构件,具有钢材和混凝土两种材料各自优点。随着钢管混凝土柱广泛应用,出现了钢管内壁与混凝土剥离和内部混凝土产生蜂窝、孔洞等质量缺陷,严重影响构件使用寿命,破坏结构工程整体承载力。敲击法、超声波法、压电陶瓷片法3种检测方法是目前针对钢管内壁与混凝土剥离缺陷的常用方法,通过试验对3种检测方法的效果进行对比分析。Steel pipe concrete column has become an important component in civil engineering,with the respective advantages of steel and concrete.With the wide application of steel pipe concrete columns,there are quality defects such as peeling of the inner wall of the steel pipe and concrete and honeycomb and holes in the internal concrete,which seriously affect the service life of the components and damage the overall bearing capacity of the structural engineering.Knocking method,ultrasonic method,piezoelectric ceramic chip three detection methods for the internal wall of steel pipe and concrete peeling defects commonly used methods,this paper presents a comparative analysis of the effectiveness of the three detection methods through testing.
