摘　　要：由于工程地质条件的复杂性,注浆材料需要满足速凝早强、抗分散性、耐久性好的要求。而纳米材料可以改善水泥基注浆材料的力学特性、抗分散性、耐久性,为注浆材料的研制提供了新方向。本文就纳米材料改性水泥基注浆材料的作用机理和研究现状进行了归纳分析,指出关于注浆参数的模型试验和数值模拟研究成果应与工程实践联系,研制更符合特定工程要求的注浆材料,为注浆实践提供指导。Due to the complexity of engineering geological conditions,grouting materials need to meet the requirements of quick setting,early strength,dispersion-resistance and good durability.Nanomaterials can improve the mechanical properties,dispersion-resistance and durability of cement-based grouting materials,providing a new direction for the development of grouting materials.In this paper,the action mechanism and research status of nano-materials modified cement-based grouting materials are summarized and analyzed,and it is pointed out that the research results of model test and numerical simulation on grouting parameters should be related to engineering practice,and the grouting materials more in line with specific engineering requirements should be developed,so as to provide guidance for grouting practice.
