摘　　要：混凝土抗拉强度是反映混凝土参数的重要指标之一,不同的测试方法对混凝土抗拉强度有一定的影响。混凝土钻取芯样作为一种成熟的技术,方便了芯样轴心抗拉试验的开展。文中采用钻芯法和钻拉法试验测定混凝土进行抗拉强度,并与现有规范中的试验所得的结果进行对比,研究测试方法对混凝土抗拉强度的影响。The tensile strength of concrete is the key index of concrete material,and different test methods have certain effects on the tensile strength of concrete.As a mature technology,concrete core drilling facilitates the development of core axial tensile test.The core drilling method,and the drilling and tensile strength method are used to measure the tensile strength of concrete,the results of which are compared with that in the existing specifications.The influence of the test methods on the tensile strength of concrete is studied.

关 键 词：抗拉强度 钻拉法 钻芯法
