摘　　要：对后锚固法检测混凝土强度试验进行相关力学分析,结果表明:后锚固法在反力环反力的作用下,存在界限破坏深度.利用智能优化算法中的经验遗传-单纯形算法进行回归分析,以试验数据为基础,采用优化算法进行数据处理,建立了后锚固法检测混凝土强度的测强曲线.This paper analyzes anchorage pullout method to check concrete strength in the case of various embedment lengths and diameter of reaction rings, and analysizes the test data and the stress of cubic element, which reveals that there is the threshold depth on the condition of definitive diameter, the pullout force will increase with the increase of the diameter of reaction rings and the decrease of threshold depth. Utilizing the result of the conclusion we will check the concrete strength more relia- bly. An intelligent optimization algorithm called empirical genetic-simplex algorithm is applied to es- tablish correlation lines based on adhesive anchorage pullout test.
