现有碳纤维增强复合材料（carbon fiber reinforced plastic, CFRP）板夹片式锚具在张拉过程中，由于锚杯上下内壁受到挤压力的作用，易产生起拱变形，进而在锚杯与夹片接触面出现“脱空”现象，这导致CFRP板锚固段在横向受力上呈现不均匀性。同时，CFRP板两侧由于应力集中，易发生劈裂破坏。为改善此问题，提出了夹片起弧式CFRP板锚具的优化设计思路，并对不同起弧高度的夹片式锚具进行了有限元数值模拟与静载张拉试验研究。研究结果表明，传统CFRP板夹片式锚具的主要破坏形式为先劈裂后拉碎，其锚固效率仅为68.75%。当夹片起弧高度较低时，无法有效填充锚杯的“脱空”，导致CFRP板锚固段整体压应力水平偏低，锚固效率下降至56.67%。相反，若夹片起弧过高（0.5 mm），则会在CFRP板锚固段中部产生应力集中，锚固效率提升至81.25%，但仍非最优。值得注意的是，当夹片起弧高度设置为0.25 mm时，锚固效率显著提高至90.83%，且破坏形式转变为爆炸式破坏，这表明CFRP材料的性能得到了充分发挥。因此，合理设置夹片起弧高度可有效防止CFRP板锚固段因“脱空”而发生劈裂破坏，研究结果具有较高的工程应用价值。

The existing CFRP(carbon fiber reinforced plastic) plate clip-type anchorage exhibits arching deformation during the tensioning process due to compressive forces on the inside wall of the anchor cup. This causes "voids" at the contact interface between the anchor cup and the clip, leading to an uneven distribution of lateral forces within the CFRP plate anchorage section. The sides of the CFRP plate are prone to cracking failure due to stress concentration. An optimized design for arching clip-type CFRP plate anchors was proposed to address this issue. Finite element numerical simulations and static loading tension tests were conducted on clip-type anchors with varying arch heights. The findings show that the primary failure mode of conventional CFRP plate clip-type anchors is initial cracking followed by fragmentation, with an anchoring efficiency of only 68.75%. When the arch height is low, the voids in the anchor cup are not adequately filled, resulting in lower compressive stress and an anchoring efficiency of 56.67%. When the arch height is too high(0.5 mm), stress concentration occurs in the middle section of the CFRP plate anchorage, which increases the anchoring efficiency to 81.25%, but this is still suboptimal. Notably, when the arch height is set to 0.25 mm, anchoring efficiency increases to 90.83%, and the failure mode shifts to explosive failure, indicating that the CFRP material has been fully utilized. The rational adjustment of the clip's arch height effectively prevents cracking failures in the CFRP plate anchorage due to voids, demonstrating the significant engineering application value of this research.
