引用本文摘 ? 要：分析了碳纖維網的密度、層數與預埋位置以及碳纖維短切絲的長度與摻量對混凝土梁抗折性能的影響。結果表明：預埋碳纖維網與摻入碳纖維短切絲均能顯著提升混凝土梁的抗折性能；碳纖維網密度為20 mm×20 mm時，距混凝土梁上表面125 mm時的增強效果最佳；雙層碳纖維網的增強效果明顯優于單層碳纖維網；同時摻入碳纖維短切絲可繼續提升混凝土梁的抗折性能，且摻量2%、長度6 mm的碳纖維短切絲提升效果最佳。 Abstract: The weakness of flexural and crack resistance has seriously affected the wide application of concrete in engineering. The influence of the density, the number of layers and the embedded position of carbon fiber mesh, and the length and content of carbon fiber short-cut wire on the flexural performance of concrete beams were analyzed. The results show that both the embedded carbon fiber mesh and the incorporation of carbon fiber short-cut wire can significantly improve the flexural performance of concrete beams. When the density of carbon fiber mesh is 20 mm× 20 mm, the reinforcement effect is the best when it is 125 mm away from the upper surface of the concrete beam. The reinforcement effect of adding double carbon fiber mesh is better than that of single layer. At the same time, adding carbon fiber short-cut wire can continue to improve the flexural performance of concrete beam, and 2% content of carbon fiber short-cut wire with the length of 6 mm is the best.
