| 摘 要： | 首先简单介绍了单轴压缩试验的具体情况。对于拉裂破坏模式,提出了相应的力学计算模型,并建立了抗压强度和抗拉强度的关系式。对于由拉裂面的存在而导致试件最终破坏的计算模型,提出了4种相应的假设。其中,对4种特征的拉裂面建立了抗压强度和抗拉强度的关系式。

| Abstract: | Firstly,simple uniaxial compression test of concrete is introduced.For tension damage model,the corresponding calculation model is put forward,and the compressive strength and tensile strength of the interrelations with each other are set up.The reason that the compressive strength is much higher than the tensile strength is analyzed.Because of the existence of tension caused by the destruction of specimen final calculation model,the corresponding four kinds of assumptions,including four kinds of characteri... |
