%X 碳纤维增强聚合物片材(CFRP)作为一种新型材料，在结构工程领域作为加固材料，通过对构件施加预应力大幅度提升结构的抗弯承载能力，常用于桥梁的加固工程中，可显著延长结构的耐久性，大幅度减少结构的维护费用，碳纤维板材料在长期受力过程中会产生蠕变和应力松弛，蠕变性能会削弱结构加固效果，进而影响结构正常工作，甚至会导致工程结构破坏从而造成巨大经济损失，因此，为保证碳纤维拉索结构的安全和耐久性，针对碳纤维板材料的蠕变性能研究十分有必要。本文主要归纳国内外对于蠕变性能的综合研究以及碳纤维拉索系统的蠕变影响因素，并探究应该如何对锚固系统锚固下的碳纤维拉索进行整体性能试验研究。<br />
Carbon fiber reinforced polymer sheet (CFRP), as a new material, is widely used in structural engineering. As a reinforcement material, the flexural bearing capacity of the structure is greatly improved by applying prestress to the components. It is often used in bridge reinforcement engineering, which can significantly extend the durability of the structure and greatly reduce the maintenance cost of the structure. In the long-term stress process, the carbon fiber plate material will produce creep and stress relaxation, and the creep performance will weaken the reinforcement effect of the structure, thus affecting the normal operation of the structure. It may even lead to structural damage and huge economic losses. Therefore, in order to ensure the safety and durability of the carbon fiber cable structure, it is necessary to study the creep properties of carbon fiber sheet materials. This paper sums up the factors influencing the creep of carbon fiber cable system, and explores how to conduct the overall performance test research of carbon fiber cable anchored by the anchoring system.
