摘　　要：对预应力碳纤维板材加固混凝土梁构件的应用做了初步的研究，提出了应用预应力碳纤维板材加固梁构件的试验施工工艺；对施加预应力后的碳纤维板与混凝土结构结合面间的粘结锚固的可靠性和通过粘结锚固能施加到混凝土结构上的有效预应力进行了试验研究。试验研究结果表明，在研究并采用了一种简单适用的新型粘结锚固措施后，碳纤维板张拉力能有效地通过粘结和锚固将预应力加到混凝土结构上，能施加的有效预应力为张拉力的65％-80％，试验结果可为工程应用提供有益的参考。It is presented a primary study of strengthening reinforced concrete beam using prestressing CFRP sheets and its processing technology of strengthening in laboratory. It was studied that the cohering properties of CFRP sheets and concrete, the measured effective prestress which could be applied to the reinforced concrete beam. By studying and adopting a new anchoring measure, prestress can be effectively transferred to the reinforced concrete beam, and the effective prestress applied to the reinforced concrete beam is 70% - 80% of the total prestress. The experimental results are valuable for applying in engineerings.
