采用一种新方法——后锚固拔出法对结构混凝土强度进行检测,通过对后锚固拔出法检测混凝土强度试验混凝土孔壁与胶体界面处微元体应力进行分析可知,后锚固拔出法在反力环直径一定的情况下,存在界限破坏深度。进一步推导理论拔出力并总结经验拔出力公式,在此基础上讨论后锚固拔出法检测混凝土强度的影响因素,利用此研究结果可较准确地检测混凝土强度,最后通过大量的试验建立了后锚固拔出法检测混凝土强度的测强曲线。 A new method, post-anchor-pullout method, was used to test the strength of structural concrete. The post-anchorage-pull-out method was used to analyze the stress of the micro-bodies at the interface between the pore walls and the colloids in the concrete strength test. In the case of a certain diameter of the reaction ring, there is a limit damage depth. Further deduce the theoretical pull-out force and sum up the formula of empirical pull-out force. Based on this, we discuss the factors that affect the concrete strength after anchoring and pulling out. Based on the results of this study, the strength of concrete can be measured accurately. Finally, Post-anchor pull test method to measure strength of concrete strength curve.
