摘　　要：本文提出了一种新型柱脚设计方案,将非金属预应力筋安装在柱脚,运用施加预应力的方法改变柱脚应力性质,使其不仅易于抗压,也易于抗弯和抗拉,改善了高强绝缘陶瓷的脆性特性,提高其韧性。针对该新型柱脚设计方案,以一实际工程为算例,进行了AFRP张拉锚固方法探究试验以及瓷绝缘柱脚抗弯试验。通过试验,总结了AFRP筋施加预拉力的方法,并分析了该新型柱脚的受力性能。In this paper, a new type of column foot was proposed. The non-metallic prestressed tendons were installed into the column foot, whose stress properties were changed using the prestressed method making it not only easy to resist to pressure, but also easy to resist to bending and tensile strength, and the brittleness of high-strength insulating ceramics was changed, the ductility was improved. Then prestressed test of AFRP tendons and bending tests of the combination of AFRP tendons and ceramics were designed to make and finish towards the new column foot on a practical project. According to the tests, the prestressed methods of AFRP tendons were concluded, and mechanical performance of the new column foot was analyzed.
