围绕国内外预应力FRP加固技术的研究现状以及最新进展，从预应力FRP加固混凝土结构、预应力FRP加固钢结构、预应力FRP加固中关键技术的研究等方面进行了综述。试验研究表明：预应力FRP加固混凝土能显著提高构件的开裂荷载、屈服荷载和极限荷载，改善受弯构件在长期荷载的力学性能，提高构件的疲劳寿命；预应力CFRP加固钢梁后，其屈服荷载和极限荷载相对于对比梁都有明显的提高，其提高的程度随着预应力CFRP的用量和预应力水平的提高而增大；预应力CFRP加固对钢梁的刚度提高作用也比较明显，对低强度的钢材，提高效果更明显；采用预应力FRP加固工程结构的关键问题在于预应力的施加体系、预应力控制值、预应力损失和端部的锚固。

The application of fiber reinforced plastics (FRP) in strengthening projects is one of the most popular fields in the studies in civil engineering. Practices and theories have testified that the technology of strengthening structures with prestressed FRP is feasible with obvious advantages. A concise state-of-the-art survey and new progress of the technology of strengthening structures with prestressed FRP are presented, including studies in terms of concrete structures strengthening with prestressed FRP, steel structures strengthening with prestressed FRP and the key problems in its practical application. Experimental studies revealed that strengthened with prestressed FRP, the cracking load, yielding load and ultimate capacity of RC beams increased obviously, behaviors of flexure members under long-term load were improved, and the fatigue life of concrete members were also increased.Strengthen steel beams with prestressed FRP, the yielding load and ultimate capacity increased obviously, with greater increase when more CFRP were used or at higher prestress level. Prestressed CFRP contributed to the rigidity of steel beam especially when strength of steel is relatively low. The key problems in practical application of the technology of strengthening with prestressed FRP include the studies on prestress applying system, prestress control value, prestress loss and end anchorage system.
