摘 要: 纤维复合材料补强加固混凝土结构是近年来出现的一种新兴的、科技含量较高的补强加固技术 ,已被应用于国内外的桥梁加固工程中。通过与传统的补强加固材料比较 ,纤维复合材料具有质量轻、比强度大、比刚度大、抗疲劳、耐腐蚀等优良的力学性能。在桥梁加固施工中 ,可以充分用纤维复合材料的高强度、高弹性模量以及施工便捷、易粘贴等特性 ,在混凝土结构的受拉区粘贴纤维复合材料 ,使混凝土结构中的裂缝扩展得到抑制 ,承载能力得到提高 ,结构受力性能得到改善 。 In recent years, the concrete structure strengthening by fiber compound material has become a newly found high technology, which is widely used in bridge strengthening works at home and abroad. By comparing with the traditional strengthening material, the fiber compound material has its excellent mechanics characteristics of light quality, big ratio intension, large ratio inflexibility, good fatigue resistance and fine corrosion resistance. The fiber compound material in tension area of the concrete structure would control the extension of cracks, then the bearing load can be increased and the structural tension improved, so as to reach the target of effective strengthening.
