摘　　要：用光弹性法分别研究了一组含软包体、等模量包体， 及硬包体的复合模型中的应力及其变化。结果表明， 在硬包体中的应力更高， 硬包体的存在乃是复合模型中形成和积累高应力区的结构构成条件， 从而为坚固体孕震模式的力学机制研究提供了基本的实验依据。A group of stress and its variation in the combination models with soft inclusion, equal modulus inclusion and hard inclusion has been studied by photoelastic method. The results show that the stress is higher in hard inclusion. The existence of hard inclusion is the forming condition of structure that forms and accumulates high stress area in the combination model. Therefore, it provides a basic test evidence for mechanical mechanism study for the seismogenic mode of hard body.
