纤维水泥土抗折强度的正交试验研究
Orthogonal tests on flexural strength of fiber reinforced cement soil

通过正交试验，研究纤维长度、纤维掺量、水泥掺入比和土样含水率等4个主要因素对纤维水泥土抗折强度的影响，采用极差分析和方差分析方法对试验结果进行分析。研究结果表明：纤维水泥土抗折强度影响因素的主次顺序为土样含水率、纤维掺量、水泥掺入比、纤维长度。
By orthogonal tests, the influence of fiber length, fiber content, cement ratio and moisture content on flexural strength of fiber reinforced cement soil was studied. The results were analyzed by range analysis and variance analysis. The results show that the above influence factors can be arranged as follows: moisture content, fiber content, cement ratio, fiber length
