In this work, the experimental study of unconfined compressive strength tests, direct tensile strength tests and three point bending tests were carried out to evaluate the effect of PVA fiber reinforcement on the mechanical behaviour of cemented silty soil. In general, the addition of polyvinyl alcohol (PVA) fiber lead to an increase in compressive strength, and it was observed more significant improvement in tensile strength and flexural strength, moreover, the inclusion of fibers effectively altered the brittle failure pattern of unreinforced cemented soil and improve the toughness and ductility. In addition, the microstructural of interaction between fibers and cemented soil was investigated. The proposal of regression model was utilized for predicting compressive strength, tensile strength and flexural strength.

在这项工作中，进行了无侧限抗压强度试验，直接抗拉强度试验和三点弯曲试验的实验研究，以评估PVA纤维增强对水泥质粉质土力学性能的影响。通常，添加聚乙烯醇（PVA）纤维会导致抗压强度的增加，并且观察到抗张强度和抗弯强度的改善更为显着，此外，纤维的掺入有效地改变了未加筋水泥土的脆性破坏模式。并提高韧性和延展性。此外，还研究了纤维与水泥土之间相互作用的微观结构。回归模型的建议用于预测抗压强度，抗拉强度和抗弯强度。
