摘　　要：层状复合岩石是工程施工中常见的岩体结构。采用相似材料制作模型,通过双轴压缩实验研究单一岩石及水平和竖向层状复合岩石相似模型的荷载变形曲线及破坏形式,在特殊加载力的作用下,岩石破坏呈现出特殊拉-剪破坏规律,实验结果表明,在双向加载状态下,中间主应力σ2对试件的破坏强度有显著影响。The stratified composite rock is familiar rock structure in project, using resemble material making model , getting the Loading-- Displacement curve and failure format which study on resemble model of simplex rock and level and vertical stratified composite rock through biaxial compression. The especial fracture was shown as pull- shear fracture on stratified composite rock through especial loading. The experiments results indicate that among the main stress has significant impact strength on the destruction intension of specimens through biaxial load state.
