在实验基础上，给出了定量描述声发射活性的特征函数，导出了声发射参数同损伤参量之间的关系及用声发射参数表示的损伤演化方程和本构方程，并通过实验，验证了演化方程的正确性。探讨了根据混凝土受载后的声发射特征来动态评价和估计混凝土材料的损伤程度问题，为混凝土损伤的研究和损伤因子的测试提供了一种新的方法和新的途径。
Based on the experiment, the quantitative description of the eigenfunction of AE activity is given, and the relationship between AE parameters and damage parameters is derived. The damage evolution equation and constitutive equation with AE parameters are given. The correctness of evolution equation. This paper discussed how to dynamically evaluate and estimate the degree of damage of concrete materials according to the acoustic emission characteristics after concrete loading. It provides a new method and a new way for the study of concrete damage and damage factors.
