基于正交试验的木质纤维土无侧限抗压强度分析

摘要

通过正交试验，分析了压实度、含水率以及纤维掺量三个因素对木质纤维加筋土无侧限抗压强度试验的影响，试验结果表明：含水率以及压实度对木质纤维土的抗剪强度指标影响非常显著，纤维掺量对无侧限抗压强度的影响有一定的显著性，木质纤维无侧限抗压强度随压实度的增长不断上升，随含水量以及纤维掺量的增大而减小。%According to the orthogonal experiment,the paper analyzes the influence of the compression,water content,and fiber mixing volume on the unconfined compressive strength experiment of the wooden fiber reinforced soil,proves by the test result that the water content and com-pression have the evident influence on the anti-shearing strength index of the wood fiber soil,the fiber mixing has certain effect on the unconfined compressive strength,and indicates the wood fiber unconfined compressive strength increases along with the rising compaction,while it lowers along with the increasing water content and fiber mixing volume.
