研究了界面区组分的梯度分布对水泥基材料层状结构力学性能的影响,在非均匀应变模型的基础上,讨论了界面区组分梯度变化所表现的界面应力行为.结果表明,界面区组分梯度分布可以有效缓解界面残余应力,从而明显改善结构整体的力学行为. The influence of gradient distribution of interface components on the mechanical properties of layered structure of cement-based materials was studied. Based on the non-uniform strain model, the interface stress behavior under the gradient of component composition was discussed. The results show that the interface region Gradient distribution of components can effectively relieve interface residual stress, which can obviously improve the mechanical behavior of the whole structure.
