摘　　要：通过进行混凝土单轴抗拉试验,发现了抗拉试验的要求及试验过程存在的主要问题。论文设计了一套新型单轴抗拉试验模具,解决了试验过程中影响试验结果的问题,并通过试验验证了模具的可用性,提高了试验数据的稳定性,对提高混凝土单轴抗拉试验的精度具有明显的作用。The requests and main problems in the process of uniaxial tensile test of concrete were understood through testing concrete and finding the related information. A new type of uniaxial tensile test mould was designed,and it was made to solve the main problems that affect the tensile test result. Experiments were tested and verified the availability of the mould. It turned out that the stability and the accuracy of the concrete uniaxial tensile test data was obviously improved.

关 键 词：新型抗拉模具 混凝土抗拉强度 单轴抗拉试验
