Abstract
In order to solve the problem that the drilling core method is more destructive to the concrete structure,the paper uses the shear method to test the shear strength of concrete test blocks of different ages and different strengths,and tests the compressive strength of the same batch of concrete test blocks,and collects the data of the compressive strength and shear strength of concrete for regression analysis.The shear strength curve between compressive strength and shear strength of early concrete in this area was established by selecting a suitable mathemati-cal model.The practice shows that the shear method has high precision,simple operation,small influence factors,small damage to the con-crete structure and does not affect its mechanical performance,and can better solve the problems of difficult operation and large dispersion of concrete components such as beams and joints with dense reinforcement in coring strength detection.关键词
