| 摘 要： | 将剪切梁层间失效模型用于分析地震的发生。将岩体简化为由弹塑性向夹层粘结在一起的剪切梁；考虑了侧压力沿竖向的变化；将地层深部产生的反平面剪切载荷作为诱发地震的原因；分析了岩体的位移和应力分布规律，得到了层间裂纹产生及其扩展规律，建立了地震发生的条件，提出了一种预报地震的方法。

| Abstract: | Shear beam model for interface failure was used for the earthquake occurring analysis in this paper. Rock body was simplified to shear beams with elastic-plastic vertical interface layer. Changes of side pressure along vertical were considered. Antiplane shear loads under deep layer were regarded as the causes for earthquake. Analytical solution was given for rule of rock displacement and stress distributions and forming and developing of the crack in interface layer. A condition of earthquake occurring was set up. A method of earthquake prediction was proposed. |
