摘　　要： 对锚固注浆材料配合比及有关性能进行了系统研究，得到了一批早强型锚固注浆材料，其水泥净浆和砂浆３ｄ抗压强度分别可达３３．０～４５．４ＭＰａ和３５．３～３８．５ＭＰａ。经现场试验检验，满足设计技术要求，可应用于三峡工程现场施工。 The proportions of mixture of the quick hardening grouting agents used for anchoring rods and its properties were systematically studied. Series of anchor grouting materials were obtained. The compressive strengths of their cement paste and cement motar at the age of 3d reach 33.0 ￣ 45.4 MPa and 35.3 ￣ 38.5 MPa respectively. By detcting in situ, the indexes of these grouting materials satisfy the design requirement, and the materials will be used for the Three Gorges Project.
