为探究掺加水泥、石灰、长安大学4号固化剂以及多种纤维的复合固化黄土的抗干湿循环性能,进行了干湿循环试验、相对动弹模量试验。试验结果表明:纤维与固化剂可以显著提高复合固化砂土的抗干湿循环性能,其中0.45%改性聚丙烯纤维、8%~10%水泥作为复合固化材料时复合固化砂土的抗干湿循环性能达到最优效果。
In order to explore the wet-dry cycle performance of mixed solidified loess with cement, lime, No. 4 curing agent of Chang’an University and various kinds of fibers, wet-dry cycle test and relative dynamic elastic modulus test were conducted. The experimental results show that the fiber and curing agent can significantly improve the dry-wet cycling performance of the composite cured sand, of which 0.45% modified polypropylene fiber, 8% to 10% cement as the composite curing material composite cured sand dry Cycle performance to achieve the best results.
