摘　　要：钢管混凝土抗震性能优、塑性变形空间大、强度高、自重轻,且工业化程度高,广泛应用于土木建筑工程领域中,但该组合结构优越性能的发挥与钢管混凝土的施工质量密切相关,因此如何准确检测钢管混凝土成品质量,计算判断可能存在的缺陷,分析其对建筑物或构筑物的影响,进而采取合适的处理措施就显得十分重要。该文通过对钢管混凝土缺陷形式及成因进行探讨,引入现有检测方法原理,结合典型应用案例的实践数据,分析不同检测方法对钢管混凝土缺陷的检测效果,可为行业从业者提供相关技术参考。Concrete-filled Steel tube is widely used in the field of civil and construction engineering because of its excellent seismic performance,remarkable plastic deformation performance,high strength,light dead load,and high industrialization degree.However,the superior performance of this composite structure is closely related to the construction quality of concrete-filled steel tube.Therefore,it is crucial to accurately detect the quality of finished concrete-filled steel tube products,calculate and judge potential defects,and analyze their impact on buildings or structures so as to take appropriate treatment measures.The detection effects of different detection methods on defects in concrete-filled steel tube are analyzed based on exploring the forms and causes of these defects,combined with the principles of existing detection methods and practical data from typical application cases,which can provide relevant technical references for industry practitioners.
