中文摘要：

对3种粗合成纤维增强混凝土的抗压、抗弯强度进行研究并绘制了荷载-挠度曲线，采用日本JSCE方法计算纤维混凝土的抗弯韧性和抗弯韧性系数。通过拔出试验对纤维与混凝土基体的界面粘结性能进行研究，绘制拔出荷载-位移曲线，并对粗合成纤维增强混凝土的机理进行分析。结果表明，此类纤维与基体的界面粘结性能优异，对混凝土有明显的增强、增韧效果。

英文摘要：

The compressive and flexural strengths of three types of synthetic structural fiber reinforced concretes are researched and the load-deformation curves are recorded. By JSCE the beding toughness and bending toughness coefficient are calculated, By pull-out experiments the interfacial bond behaviour between fiber and concrete matrix are researched and the pull-out load-displacement curves are recorded. The mechanisms of fiber reinforced concretes are analyzed. Results show that the interracial bond behavior is excellent and concretes are reinforced and toughened with these fibers.
