| 摘 要： | 对一种新型水泥混凝土桥面铺装材料——钢纤维增强聚合物改性混凝土的疲劳性能进行了研究，采用三点弯曲梁试件进行了等幅疲劳实验，建立了S-lgN单对数疲劳方程，并与钢纤维增强混凝土在循环荷载作用下的弯曲疲劳性能进行了比较和分析．结果表明，钢纤维增强聚合物改性混凝土比钢纤维增强混凝土具有更好的抗疲劳性能。

| Abstract: | The fatigue behavior of a kind of new cement concrete bridge deck pavement material-Steel Fiber Reinforced and Polymer Modified Concrete (SFRPMC) is studied. Equal amplitude fatigue experiments are carried out on three-point bending samples. Single-log fatigue equation S-lgN is derived. The differences of the bending fatigue properties between Steel Fiber Reinforce Concrete (SFRC) and SFRPMC are compared and analyzed. The results show that the SFRPMC exhibit better fatigue behavior than SFRC. |
