DIP技术在单粒径骨料粒形参数与其架构型式相关性研究中的应用

Application of DIP Method in Research on the Relativity between the Single-particle-sized Coarse Aggregate Shaping Parameter and Its Framework Form

运用数字图形处理DIP技术研究了骨料的粒形特征,并采用球度和扁平比两个参数作为其粒形特征参数。通过研究单粒径的堆积空隙率,利用MATLAB进行数据处理,建立空隙率和骨料粒形参数的数学模型,结合混凝土架构模型理论,建立了骨料粒形参数与其架构型式的相关性。

Here is a research on the aggregate ＇s characteristic sizes by digital image processing DIP method. By adopting the two parameters of sphericity and thickness - breadth ratio as the parameters of the characteristic sizes, studying the deposit ratio of the single particle size, and using MATLAB in digital processing, the math model is set up between the voidage and the shaping parameter of coarse aggregate. Combined with the concrete framework model theory, relativity between the shaping parameter of coarse aggregate and its framework form is established as well.
