中文摘要:
      为定量描述纤维增强高性能混凝土(FRHPC)的破坏过程及机理,运用断裂力学理论并引入孔隙分形维数,在测试了25组不同水胶比、不同养护制度试件的抗压强度、孔结构参数的基础上,建立了FRHPC的破坏概率模型.该模型不仅考虑了孔隙分形维数对基体裂缝复杂程度的影响,还考虑了纤维增强系数对基体失效概率的影响.模型回归分析结果表明:根据该模型计算的FRHPC破坏概率与破坏概率试验值有较高相关性,为定量表征FRHPC的破坏过程及机理分析提供了一种全新的视角和思路,也从侧面验证了模型的科学性与实用性.
英文摘要:
      In order to describe destruction process and mechanism of the fiber reinforced high performance concrete (FRHPC) quantitatively, the failure probability model was established by using the pore fractal dimension and fracture mechanics theory through the compressive strength and pore structure parameters of 25 groups specimens with different water binder ratio and different curing system. This model considers not only the effect of pore fractal on the fracture complexity of the matrix, but also the effect of the fiber enhancement coefficient on the failure probability of the matrix. The regression analysis for this model shows that the probability of model calculation has a higher correlation with the test, which provides a new perspective and thinking of representation about the destruction process and mechanism of FRHPC quantitatively, and also verify the scientificity and practicability of the model at the side.
