Abstract: The concrete members always appear owing to loading change, temperature effect, design, construction and original materials. Those cracks become the perils for safety operation, composite fiber with high intension has been used for reinforcement, which can eliminate the perils effectively, meanwhile, the construction is simple and convenient.

摘要： 混凝土构件由于荷载的变化，温度的作用以及设计、施工、原材料等多种因素的综合影响，运行中会出现裂缝，这些裂缝是混凝土构件安全运行的隐患。采用高强复合纤维进行补强加固，可有效消除这一隐患，且施工方法简便。
