| 摘要: | 力学性能优异的碳纤维增强复合材料(CFRP)在桥梁工程中具有广泛的应用前景, 然而CFRP材料及其与桥梁结构组合体系的耐久性还有待研究. 笔者对近年来对CFRP材料、CFRP材料加固混凝土梁(柱)、CFRP筋－混凝土主梁的耐久性及劣化机理等问题的研究成果进行系统的归纳和总结. 指出: 桥梁用CFRP材料多因素耦合环境加速腐蚀试验方法、CFRP材料应用于桥梁工程的防腐措施、CFRP材料与结构的组合界面力学行为随环境变化的规律、含CFRP材料的桥梁结构耐久性年限理论预测模型以及CFRP拉索和预应力筋的锚固体系耐久性等有待进一步研究. |
| Abstract: | Carbon fiber reinforced plastic has the excellent mechanics performance showing good application prospects in bridge engineering. However, the durability of CFRP material and the bridge structure that contain the materials should be studied in advance. The durability research progresses of CFRP-bridge composite structure are reviewed, and the research results have been summarized systematically. It focuses on the durability and deterioration mechanism of the CFRP materials, concrete beams or pillars reinforced with CFRP, and CFRP rod-bridge composite structure. The results show that the accelerated corrosion testing methods and the multi-factor coupling are still far from mature. It lacks anti-corrosion measures for CFRP-bridge composite structure. The mechanics behavior variation laws of the interface of CFRP-bridge corresponding to environmental changes need further investigation. The durability theoretical prediction model of CFRP-bridge composite structure should be established, and thus far the durability of the anchorage systems of CFRP strand and rods has not been fully studied. |
