摘要: 针对目前FRP材料在土木工程领域中的研究现状,在阅读大量国内外相关资料的基础上,简单介绍了FRP复合材料加固技术的发展,并重点分析了内嵌预应力FRP板或筋材加固法的特点及工程应用方面的若干问题。通过分析得到,内嵌预应力FRP板条或筋材加固法是一种有效的加固技术,但实用的张拉锚固技术及影响加固效果的相关参数研究有待进一步深入探讨。

Abstract: According to the research status of FRP materials, the development of FRP reinforcement technology was introduced based on literatures at home and abroad. And, the characteristics of NSM prestressed FRP and some engineering application problems were analyzed. The results show that NSM prestressed FRP reinforcement is an effective strengthening method. However, some factors such as practical tension and anchor system and different parameters should be further explored.

Key words: concrete struction, strenthening, FRP, pretressing
