摘　　要：对于缺少砂石等材料地区的工程建设而言,水泥土是一种性价比较高的建材,但由于缺少粗骨料支撑,其抗裂和抗拉性能存在不足,难以满足更高的应用需求。纤维材料的抗拉性能优异,将其作为增强材料掺入水泥土中,借助纤维增强原理可实现水泥土抗裂性能的提升。基于此,开展了无侧限抗压强度和劈裂抗拉强度试验,研究了养护龄期、水泥质量分数对水泥土力学强度的影响规律,并进一步分析了玄武岩纤维和玻璃纤维及其质量分数对水泥土力学强度的增强效果。研究结论可为纤维水泥土的实际应用提供理论指导。For engineering construction in areas lacking of sand and gravel,cement soil is a kind of building material with high cost performance.However,due to the lack of coarse aggregate support,its crack resis⁃tance and tensile properties are insufficient,and it is difficult to meet higher application requirements.Fi⁃ber materials has excellent tensile properties,by adding it into cement soil as a reinforcement material,the anti cracking performance of cement soil can be improved with the help of fiber reinforcement principle.Based on this,the unconfined compressive strength and splitting tensile strength tests were carried out,the influences of curing age and cement mass fraction on the mechanical strength of cement soil were studied,and the strengthening effects of basalt fibers and glass fibers and their mass fraction on the mechanical strength of cement soil were further analyzed.The research results can provide theoretical guidance for the practical application of fiber reinforced cement soil.
