| 摘 要： | 本文分析了聚丙烯纤维掺入量及水泥的掺入量对水泥土强度和弹性模量影响的机理,通过试验分析表明,纤维的掺入量在一定的范围内,水泥土的强度随纤维掺入量的增加而增大,当纤维的掺入量超过这个范围其强度反而降低,而弹性模量随纤维掺入量的增加而减小;当纤维掺入量固定不变时,水泥土的强度和弹性模量随着水泥的掺入量增加而增大。

| Abstract: | The effects of content of polypropylene fibers and cement on the strength and elastic mod-ules of soil-cement mixture were studied.The results show that the strength of soil-cement mixtures was increased with the content of fibers below certain value.When the content of fibers was over the value,the strength of soil-cement specimens subsequently fell off.The elastic modules of soil-cement were decreased with the content of fibers.Both strength and elastic modules of soil-cement were increased with the content of cement. |
