| 摘 要： | 通过对不同尺寸的混凝土试件进行巴西劈裂试验，研究了混凝土试件高径比对巴西劈裂试验结果的影响，确定了混凝土试件巴西劈裂试验的合理高径比。实验结果表明：混凝土试件在巴西劈裂试验过程中主要分为四种破坏模式。对于不同尺寸的混凝土试件，高径比为0.5或1.0的混凝土试件均可以通过巴西劈裂试验得到抗拉强度。然而，高径比为1.0的混凝土试件稳定性明显优于高径比为0.5的混凝土试件。在试件个数有限的情况下，建议采用高径比为1.0的试件进行混凝土巴西劈裂试验。

| Abstract: | based on the different sizes of Brazilian splitting test specimens of concrete, concrete specimen is studied high diameter ratio on the Brazilian spliting test results, determine the concrete reasonable high aspect ratio of Brazilian spliting test specimens. The experimental results show that the main process of concrete specimens in the Brazilian spliting test is divided into four kinds of failure mode. To the concrete samples of diferent size, high ratio of 0.5 or 1.0 of concrete specimen by Brazilian spliting tensile strength test. However, high ratio of 1.0 is obviously beter than the stability of concrete specimens of concrete specimen of high aspect ratio of 0.5. In the case of a limited number of specimens, it is recommended that the high ratio of 1.0 Brazilian split test specimens of concrete. |
