摘　　要：通过对三种不同强度等级的高性能水泥复合砂浆基材中的植筋拉拔试验,研究普通钢筋在无机植筋胶的作用下与高性能水泥复合砂浆的粘结锚固性能。归纳出典型的破坏形态,用双因素分析法分析钢筋直径、锚固深度和高性能水泥复合砂浆强度对植筋极限承载力的影响程度,对试验数据用tablecurve3D软件进行回归,拟合出实用的极限承载力计算公式。Experimental research on the behavior of inorganic adhesive steel bar in high performance cement-mortar under tensile load is finished. The failure forms arc investigated. Two factors analysis of variance is used to carry out the influence degree of the diameter,the anchorage depth and the strength of high performance cement-mortar on the ultimate anchorage strength. Calculation formula of the ultimate anchorage strength is drew up with table curve 3D.
