钢管混凝土叠合柱是在钢筋混凝土柱中部设置钢管混凝土的一种叠合构件，其缺陷检测已是工程检测领域面临的重要问题。弹性波 CT 技术是一种发展迅速的工程无损检测技术，能够直观、准确地显示出物体的内部缺陷。针对影响叠合柱性能的空洞与脱空缺陷，探索了弹性波CT无损检测技术，设计了带空洞素混凝土柱、带空洞叠合柱、带脱空叠合柱三个试件，并开展了叠合柱弹性波CT缺陷检测试验。研究结果表明，弹性波 CT 能够有效地检测叠合柱的空洞与脱空缺陷，填补了叠合柱缺陷检测领域的空白。
鋼管混凝土疊閤柱是在鋼觔混凝土柱中部設置鋼管混凝土的一種疊閤構件，其缺陷檢測已是工程檢測領域麵臨的重要問題。彈性波 CT 技術是一種髮展迅速的工程無損檢測技術，能夠直觀、準確地顯示齣物體的內部缺陷。針對影響疊閤柱性能的空洞與脫空缺陷，探索瞭彈性波CT無損檢測技術，設計瞭帶空洞素混凝土柱、帶空洞疊閤柱、帶脫空疊閤柱三箇試件，併開展瞭疊閤柱彈性波CT缺陷檢測試驗。研究結果錶明，彈性波 CT 能夠有效地檢測疊閤柱的空洞與脫空缺陷，填補瞭疊閤柱缺陷檢測領域的空白。

Steel tube-reinforced concrete column is a laminated column type which has a concrete-filled steel tube in the centre of reinforced concrete,defect detection of which is important problem in engineering detection field.Elastic wave CT de-veloping rapidly as a kind of engineering nondestructive testing technology,can intuitively,accurately show internal defect. The paper explored elastic wave CT nondestructive testing technology for cavity and empty in steel tube-reinforced concrete column.Three specimens,one concrete column with cavity,one steel tube-reinforced concrete column with cavity and one steel tube-reinforced concrete column with empty between steel tube and concrete was designed for the experiment research of defect detection for steel tube-reinforced concrete column by elastic wave CT.The results show that cavity and empty in steel tube-reinforced concrete column can be effectively detected by elastic wave CT,which will fill the blank in defect detection for steel tube-reinforced concrete column.
