预应力CFRP加固法在桥梁工程中的应用现状及展望

The Applying Status Quo and Prospects of CFRP-Strengthened Pre-Stressed Method in Bridge Project

预应力CFRP加固法较非预应力CFRP加固法更能发挥CFRP高强的材料性能,具有更加广阔的应用前景。本文就预应力CFRP加固法的材料特点、预应力施加工艺、应用进展以及国内外的研究现状作了总结,并展望了此方法的未来研究方向。

CFRP-strengthened pre-stressed method can take advantage of the material properties of high strength of CFRP compared to CFRP-strengthened non-pre-stressed method.This work summarizes the material properties of CGRP-strengthened pre-stressed method,pre-stressing process,application progress and research situation at home and abroad.In addition to the above,it also prospects the direction of future research of CFRP-strengthened pre-stressed method.
