摘要
从混凝土内部结构特征出发 ,既注意到混凝土内部各局部单元微观变形不协调性的基本特性[1] ,又注意到混凝土内部基相结合面和原生微裂纹等随机分布的缺陷所导致的破坏呈有先有后局部化发生发展的微细观基本特性 ,全面深入探讨了受压和受压剪的条件下混凝土破坏发生和发展的内在机理 ,并通过实例分析了这种内在机理的客观性 .
In this article, based on the structural property of concrete's in terior structure, in consideration of the basis property of inhomogeneity of microscopic deformation of concrete's interior each local unit as well as microscopic basic property of destruction, caused by some random flaws on binding faces of its interior structure and initial microscopic crevices, taking place and developing successively in each different local, the interior mechanism of concrete destruction from occurrence to development under compression stress as well as compression and shear stresses are thoroughly and deeply discussed. Combined with an experimental example, the objectivity of the interior mechanism is analyzed.
