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。 The anchorage-anchorage performance of ordinary steel bars with high-performance cement composite mortar under the effect of inorganic anchorage glue was studied through the test of bar anchorage in three kinds of high performance cement composite mortar substrates with different strength grades. The typical failure modes were summarized. The influence degree of reinforcement diameter, anchorage depth and strength of high performance cement mortar on the ultimate load bearing capacity were analyzed by two-factor analysis. The experimental data were regressed with tablecurve3D software to fit the practical limits Bearing capacity calculation formula.
