Abstract:
      In this paper, based on the prosperity of the concrete with multi-graded rocks, the finite method based on multi-scale analysis for the mechanics parameters of the concrete with multi-graded rocks is presented. Firstly, based on the properties of the concrete with multi-graded random rocks, the multi-scale representation model of the concrete is given. Secondly, based on the two-scale analysis and the finite element method, the procedure of the multi-scale finite element method for the concrete with rocks is introduced. Finally, a numerical example of the concrete in Xiaowan dam project illustrates that the algorithm is valid. The algorithm can also be extended to the materials with cracks, cavities or other polyhedron grains.
