摘　　要：为研究麦秸秆纤维对水泥土的加筋作用,通过无侧限抗压试验和抗折试验,得出水泥土的最优配合比,在此基础上掺入麦秸秆纤维,改变纤维掺量和纤维长度,再次进行抗压试验和抗折试验,探究二者对麦秸秆纤维水泥土强度的影响。试验结果表明:水泥土的无侧限抗压强度和抗折强度均随养护龄期和水泥掺量的增加而提高,麦秸秆纤维的掺入进一步提升了其强度;当纤维掺量为0.2%、纤维长度为10 mm时,抗压强度最大且比素水泥土提高了21.8%,在纤维掺量为0.2%、长度为15mm的条件下,试样的抗折强度相比素水泥土增幅达75.6%。To investigate the reinforcing effect of wheat straw fiber on cemented soil,unconfined compressive strength tests and bending tests were conducted to determine the optimal mix ratio of cemented soil.Based on this,wheat straw fiber was incorporated,with variations in fiber content and length,and the compressive and bending tests were repeated to explore the influence of these factors on the strength of wheat straw fiber-reinforced cemented soil.The results indicate that both the unconfined compressive strength and bending strength of the cemented soil increase with the curing age and cement content.The incorporation of wheat straw fiber further enhances its strength;when the fiber content is 0.2%and the fiber length is 10 mm,the compressive strength reaches its maximum,which is 21.8%higher than that of plain cemented soil.Under the conditions of a fiber content of 0.2%and a length of 15 mm,the bending strength of the samples increases by 75.6%.
