摘　　要：为了研究玄武岩纤维(BF)布抗剪加固破损钢筋混凝土深梁的应变变化规律,对6根破损的钢筋混凝土深梁进行抗剪加固处理,对加固后的钢筋混凝土深梁进行二次加载试验。研究不同剪跨比、不同粘贴方式下钢筋混凝土深梁的破坏过程、破坏形态及玄武岩纤维布和混凝土的应变分布规律以及不同因素对应变分布的影响,为抗剪加固破损钢筋混凝土深梁的理论计算分析奠定基础。In order to study the change regularity of strain of shear-strengthened damaged RC deep beams with basalt fiber reinforced polymer （BFRP） sheets, six damaged RC deep beams were tested after being shear-strengthened using BF sheets. The failure process and failure mode of the six damaged RC deep beams were studied with different shear span ratio and different ways of paste. And, the strain distribution rules of BF sheets and concrete and the different factors that affect the strain distribution were also analyzed. It lays the foundation for the theoretical calculation analysis of shear-strengthened damaged RC deep beams.
