纤维复合材料加固桥梁技术研究
|
摘要
对纤维复合材料(FRP)加固技术的技术原理、研究现状、施工工艺及要求、技术特点及适用范围进行总结。FRP加固技术具有施工便捷、不受构件形状限制、不改变截面尺寸、对原结构不产生损伤、优异的耐久性能、不增加自重、不减小净空及具有良好的适应性等优势。给出一些纤维复合材料加固技术在桥梁加固工程中的应用实例及加固思路,FRP加固可适用于桥梁工程中的抗弯加固、抗剪加固、约束加固及耐久性加固等不同加固情况。
The strengthening technology with fiber reinforced polymer(FRP) was summarized in this paper from aspects of principles,research status,construction process and requirements,technical characteristics and application scope.FRP reinforcement technology has many advantages such as convenient construction,unrestricted by component shapes,no change of the section size,undamaged to the original structure,excellent durability,without additional weight,no space reduction and good adaptability.The reinforcement idea and some examples in bridge strengthening projects with FRP were given.FRP reinforcement technology could be applied to flexural strengthening,shear strengthening,confinement strengthening and durability strengthening of bridges for different purposes.
