| 摘 要： | 本文把混凝土视为由骨料，基质，交界面微裂纹等组成的非均质多相体，根据非均质材料接触面上裂纹其应力奇异性不是ｒ的（－１／２）次方的特点，利用 Ｋｏ 应力函数解作为积分方程的核函数；再考虑弯曲裂纹的特点和相互干涉作用，研究混凝土骨料和基质接触面裂纹对材料断裂性能的影响．

| Abstract: | It regards concrete as a heterogeneous material the composites of aggregate, ma- trix and microcracking between aggregate and matrix. Considering that the stress singularity of microcracking in no longer power of (-1 / 2) order and using the K function as a kernel of integral equation, the character of curved crack and interaction to each other, and then Find out the effect of microcracking on fracture of concrete are researched. |

| Keywords: | concrete nonhomogeneity microcracking |
