| 摘 要： | 通过4根加配横向预应力筋的钢筋混凝土梁和1根普通钢筋混凝土梁的对比试验，初步考察了横向预应力筋对提高钢筋混凝土梁斜截面抗裂性能的良好效果。研究结果表明：（1）加配横向预应力筋并施加适当预应力能有效提高钢筋混凝土梁的斜截面抗裂能力；（2）在横向预应力筋的总截面面积一定的情况下，采用直径较小的横向预应力筋和较小的间距，能最有效的提高钢筋混凝土梁的斜截面抗裂能力。

| 关 键 词： | 横向预应力混凝土梁，斜截面抗裂性能，最大斜裂缝宽度 |

| Abstract: | A experiment that contrasted four transverse prestressed concrete beams with one ordinary reinforced concrete beam was conducted to study the good influence of transverse prestressed bars on the inclining crack resistance of the reinforced concrete beam .Analysis results showed that: (1) Reinforced concrete beams with the transverse prestressed bars with appropriate initial prestress can improve the inclining crack resistance of the reinforced concrete beams efficiently. . (2) Under the condition of the same area of bars, the transverse bars with smaller diameter and smaller spacing can improve the inclining crack resistance of the reinforced concrete beams more efficiently. |

| Keywords: | transverse prestressed concrete beams the inclining crack resistance the maximum width of inclining crack |
