摘要
介绍了某预应力混凝土井字楼盖的裂缝情况及修复处理,通过分析裂缝的成因,说明了在预应力混凝土的设计中,轴向压缩变形控制的重要性,并对预应力结构的选型进行了简要分析。
The crack conditions and its repair treatment of some prestressed concrete floor slab with cross - beam were introduced, and the importance for control of axial compression deformation in design of prestressed concrete was given through analysis of cause of crack,and brief analysis for selection of structure was made.
