| 摘 要： | 从细观层次上分析了混凝土的内部结构,把混凝土看作是由粗骨料、硬化水泥砂浆及两者之间的过渡层组成的非均匀三相复合材料。介绍了混凝土细观结构的界面元离散仿真模型计算方法,论述并验证了该细观模型的正确性,对混凝土试样在单轴荷载作用下的破坏过程和裂纹扩展过程进行了数值模拟。

| Abstract: | Concrete is taken as three phases' composites consisting of aggregate,matrix and bond between matrix and aggregate on meso-level.The model and arithmetic of Interface Element Method(IEM) is introduced to illustrate and verify the correctness of this meso-model.And the devastation process and fracture enlarging process of concrete sample under uni-axial loading are simulated numerically. |

| Keywords: | concrete microscopic IEM(Interface Element Method) numerical simulation |
