摘　　要：通过对水泥基无机黏结材料植筋承载力的拉拔试验研究,分析了水泥基无机黏结材料植筋的破坏形态和破坏机理,讨论并给出了极限锚固承载力计算公式及建议施工锚固长度表格.通过与同条件下预埋钢筋、植筋后绑焊以及某有机黏结材料植筋承载力相比得到此水泥基无机黏结材料的工程适用性,并在实际工程中得到验证.Based on the bearing capacity experimental investigation of bonded rebar by using the cement based inorganic anchoring material, failure form and mechanism of this material is analyzed. A corresponding calculating formula on the ultimate anchoring strength of this material and a suggested table in construction of anchoring length are put forward. By comparing the ultimate bearing capacity with embedded bar in advance in the same condition, welding on bonded rebar and bonded rebar by using the organic cement based inorganic anchoring material is obtained, and anchoring material, the engineering applicability of the tested in the actual project.
