摘　　要：利用MTS材料测试系统,对不同纤维长度和掺量下的聚丙烯纤维水泥稳定粒料的抗冲刷性能进行了试验研究,并与普通水泥稳定粒料进行了对比,分析了纤维的增强机理。结果表明,聚丙烯纤维的掺入显著提高了水泥稳定粒料的抗冲刷性能,合理纤维配比下,提高幅度达40%以上;短时间不如长时间的冲刷试验更能准确反映材料的抗冲刷性能;纤维对水泥稳定碎石抗冲刷性能的增强效果优于对水泥稳定砂砾的增强效果。最后,推荐了一组经济合理的纤维配合比。Using MTS,series of experiments to research the anti-erosion ability of cement-stabilized grain with fiber of different length and volume percentage were carried out,the test results of specimens with and without fiber were compared,and the anti-erosion mechanism of fiber were analyzed.The results indicated that polypropylene fiber can effectively enhance grain's anti-erosion performance,up to more than 40% when appended with a reasonable fiber mixture ratio.The research showed that grain's anti-erosion abi...
