摘　　要：由于设计、施工、材料等多方面的原因，混凝土“T”梁开裂问题一直以来难以解决，如何能解决“T”梁开裂问题成为工程界广泛研究的一项内容。本文以某工程中混凝土“T”梁腹板开裂问题为研究对象，深入研究了裂缝出现的原因，并针对这种情况提出了相应的防治措施。将普通混凝土更换为高性能混凝土以后，“T”梁裂缝问题得到了很好的解决，高性能混凝土对防治“T”梁裂缝方面具有十分明显的优势。As the reason of design, construction, materials, and many other reasons, concrete ＂T＂ beam cracking problem has been difficult to solve, how to solve the ＂T＂ beam cracking as a study content in the engineering sector. In this article we study the reason of ＂T＂ beam＇ s web cracks of one project, and corresponding measures for this case. When we replaced the ordinary concrete to high-performance concrete, the ＂T＂ beam＇ s crack has been good solution, high-performance concrete has a very clear advantage in prevention ＂T＂ beam cracks.
