为研究不同因素对木质纤维加筋土抗剪强度的影响,以黑龙江某工程的粉质黏土为试验对象,通过正交试验,得到了压实度、含水率以及纤维掺量3个因素对木质纤维加筋土抗剪强度的影响。研究结果表明:各个影响因素对土体抗剪强度指标的影响程度的次序为:含水率>压实度>纤维掺量;通过方差分析,含水率对于木质纤维土的抗剪强度参数的影响最为显著,为主要影响因素,压实度以及纤维掺量对于木质纤维加筋土黏聚力的影响较显著,属于次要影响因素。
In order to study the influence of different factors on the shear strength of wood fiber reinforced earth, with the silty clay of a project in Heilongjiang as the test object, through orthogonal test, the compaction degree, moisture content and fiber content were obtained. Effect of Fiber Reinforced Soil on Shear Strength. The results show that the order of influencing factors on the shear strength index of soil is as follows: moisture content> compaction degree> fiber content. By means of analysis of variance, the influence of water content on the shear strength parameters of lignocellulose soil is the most Significantly, the main influence factors, compaction degree and fiber content have a significant effect on the cohesion of wood fiber reinforced earth, which is the secondary factor.
