摘　　要：通过使用后植筋拔出法得到不同强度等级混凝土的拉拔力,其中主要介绍了后植筋拔出法的操作方式;另外,还通过抗压强度实验获取不同强度等级混凝土的强度。实验完成之后即可获得不同强度等级混凝土的拉拔力和抗压强度,然后通过归纳法对这些数据进行分析,利用回归方式得到混凝土强度和拉拔力之间的曲线,并且对曲线的精确度进行检测,结果表明,在混凝土强度技术检测中使用后植筋拔出法获得的回归方程具有可行性,在一定条件下能够有效根据拉拔力计算出混凝土强度。The paper uses the post-planting bar pull-out method to obtain the pull-out force of different strength grades of concrete,which mainly introduces the operation method of the post-planting bar pull-out method;in addition,the strength of different strength grades of concrete is obtained through the compressive strength experiment.After the experiment is completed,the pull-out force and compressive strength of concrete of different strength grades can be obtained,and then these data are analyzed by induction method,and the curve between concrete strength and pull-out force is obtained by regression method,and the accuracy of the curve is obtained.The test results show that the regression equation obtained by the post-planting bar pull-out method in the concrete strength technical test is feasible,and the concrete strength can be effectively calculated based on the pullout force under certain conditions.
