为了分析聚丙烯纤维对再生混凝土抗裂性能和极限承载力的影响，对10根梁构件进行了受弯试验及对比分析，结果表明：聚丙烯纤维提升混凝土抗裂性能效果显著，同时采用规范公式计算得出了构件极限受弯承载力与实测值相差小于2%，证明了采用规范公式计算的可行性。
為瞭分析聚丙烯纖維對再生混凝土抗裂性能和極限承載力的影響，對10根樑構件進行瞭受彎試驗及對比分析，結果錶明：聚丙烯纖維提升混凝土抗裂性能效果顯著，同時採用規範公式計算得齣瞭構件極限受彎承載力與實測值相差小于2%，證明瞭採用規範公式計算的可行性。

In order to analyzes the influence of the polypropylene fiber recycled concrete beam crack resistance and the ultimate bearing capaci-ty,the paper undertakes the flexural test and comparative analysis of the ten beam components,indicates by the result that the polyprophlene fi-ber can promote the concrete crack resistance performance obviously,concludes the discrepancy between the ultimate flexural bearing capacity of the components and the factual measured value is less than 2% by adopting the regular calculation,and proves the regular formula is feasible.
