以国内首座CFRP索斜拉桥上使用并获得国家专利的直筒加内锥式锚具为研究对象,选取CFRP筋所受径向挤压应力作为主要研究参数,对其进行影响因素的分析,并提出相应的优化方案。研究表明:采用优化方案后,锚具的挤压应力在锚固长度范围内有所减少且分布更趋于均匀,锚固能力较原锚具也有所提高,说明优化方案是可行的。 Taking the first type of straight-in-chin and inner-cone anchors used in China’s first CFRP cable-stayed bridge as the research object, the radial compressive stress on the CFRP tendons was selected as the main research parameter, and the influencing factors were analyzed. Put forward the corresponding optimization plan. The results show that the compressive stress of the anchorage decreases and distributes more uniformly in the length of the anchorage, and the anchoring capacity is also higher than that of the original anchorage, which shows that the optimized scheme is feasible.
