| 摘 要： | 在硅粉水泥土中掺加聚丙烯纤维配制试样,进行无侧限抗压强度试验和不同围压下的三轴试验,结果表明:聚丙烯纤维的掺加可以有效提高水泥土体的强度,且土体强度随纤维掺加量的增加而增强;随着围压的提高,水泥土试件的破坏应力和破坏应变均逐渐增大,掺入聚丙烯纤维的水泥土试件在不同围压下的破坏应力均高于同条件下未掺加纤维的试件。

| Abstract: | On the basis of silica fume soil-cement,by means of laying the polypropylene fiber into the silica fume soil-cement made up samples to conduct unconfined compression test and triaxial test in different confining pressure.The results show that polypropylene fibers can effectively improve the soil-cement strength,and the strength increases with fiber content increasing;with improving the confining pressure,the failure stress and failure strain of soil-cement samples increases gradually,and the failure stress of soil-cement samples with polypropylene fiber is higher than that soil-cement samples without polypropylene fiber. |

| Keywords: | soil-cement polypropylene fiber compressive strength triaxial test |
