摘要:
为解决软土地区桥涵台背回填中流态粉煤灰材料因沉降收缩和干燥收缩引起的开裂问题,本文通过在流态粉煤灰中掺入0.2%~1.0%(质量分数)的碱处理芦苇纤维,研究芦苇纤维增强流态粉煤灰轻型路基填料的力学性能,并结合扫描电子显微镜分析了材料的微观结构演化机理。结果表明,芦苇纤维最佳掺量为0.4%,相比于未掺芦苇纤维的对照组,此掺量下的复合材料90 d干缩值降低25.8%,180 d抗压强度提高12.8%,90 d劈裂抗拉强度提高21.2%;28与90 d水稳定系数分别提升至0.938和0.969,90 d冻融循环稳定系数达0.941;当芦苇纤维掺量超过0.6%后,复合材料的整体性能下降。微观结构分析显示,芦苇纤维在养护后期与基体形成致密的凝胶桥接结构,有效提高了材料的抗裂性、强度与长期耐久性。
