| 摘 要： | 混凝土的抗剪强度关系到混凝土结构的安全。采用随机骨料模型模拟混凝土的细观结构,利用有限元方法数值模拟混凝土试件的细观损伤断裂和抗剪强度,将所得数值结果与混凝土重力坝设计规范参考值比较,结果较为吻合,从而为混凝土力学性能的数值模拟开辟了新途径。同时研究表明混凝土试件的抗剪强度存在明显的尺寸效应。

| Abstract: | The shear strength of concrete has important effects on the safety of concrete. The random aggregate model is used to simulate concrete structures. The extension of cracks and the mechanic properties of concrete in shear tests are simulated with the finite element method. The simulation results are up to the Design Specification and test results. The size effects on the shear strength of concrete are studied too. |
