摘要
构建能充分反映混凝土实际微、细观结构特征的数值模型是混凝土力学仿真分析的基础与前提。在分析混凝土微、细观结构特征的基础上,将混凝土的微、细观结构分为三个尺度层次,分别对应为混凝土材料、水泥砂浆和水泥净浆三种水泥基材料,并逐一建立主要微细观结构的定量描述函数,实现了混凝土多尺度模型的构建。该研究可为混凝土多尺度数值分析和理论研究提供参考。
The establishment of numerical model which can fully reflect the actual micro and micro structure characteristics of concrete is the foundation and premise of the simulation analysis of concrete mechanics.Based on the analysis of the micro and micro structure characteristics of concrete,the micro and micro structure of concrete is divided into three scale levels,corresponding to three kinds of cement-based materials,namely concrete material,cement mortar and cement paste.Subsequently,the quantitative description function of the main micro structure is established and the multiscale model of concrete is realized.This study provides a reference for the multi-scale numerical analysis and theoretical research of concrete.
