Grouting material is the core force transfer medium of grouting sealing and anchorage reinforcement methods for cracks in earthen sites; the performance of grouting slurry is the key to affecting the reinforcement effect. To solve the problems of poor flexural strength, easy shrinkage and cracking of existing grouting slurry, using Glutinous Rice Pulp, Calcined Ginger Nuts, and Loess Soil as substrates, and choosing the content and length of basalt fiber (BF) as control variables, 13 groups of specimens were designed by orthogonal test method to explore the influence of mixed fiber on the mobility, shrinkage, compressive, and flexural strength. The microstructure was analyzed by SEM to explain the strengthening mechanism from physical and chemical perspectives. The results show that the mobility decreases linearly with the increase in BF content and length; after mixing BF, the shrinkage rate is significantly reduced, but when the fiber length and content are relatively high, the surface is prone to cracking. The excellent bridging ability of BF can effectively improve the compressive and flexural strength of the specimen. When the fiber length and content are high, the specimen shows certain ductile failure characteristics, and the fracture energy increases more than 10 times.

玄武岩纤维作为天然增强材料，提高土遗址保护生态灌浆浆的性能

灌浆材料是土场地裂缝灌浆封堵和锚固加固方法的核心传力介质；注浆浆的性能是影响加固效果的关键。针对现有注浆浆抗折强度差、易收缩、开裂的问题，以糯米浆、姜仁、黄土为基材，以玄武岩纤维（BF）含量和长度为控制变量，13采用正交试验方法设计多组试件，探讨混合纤维对流动性、收缩率、抗压、抗弯强度的影响。通过SEM分析显微组织，从物理和化学角度解释强化机制。结果表明，随着BF含量和长度的增加，迁移率呈线性下降；掺入BF后，收缩率明显降低，但当纤维长度和含量较高时，表面容易出现开裂。BF优异的架桥能力可以有效提高试件的抗压和抗弯强度。当纤维长度和含量较高时，试件表现出一定的延性破坏特征，断裂能增加10倍以上。
