摘　　要：为了提出基于构造控制的岩质边坡破坏模式识别方法,以某路堑边坡为例,根据优势结构面理论,运用赤平极射投影法,分别对单组结构面与边坡面的组合关系和多组结构面与边坡面的组合关系进行了研究,分析了不同情况下边坡岩体结构的稳定状态,进而对边坡破坏模式进行了识别。研究结果表明:所提出的判别原理和识别方法可以反映构造控制的岩质边坡破坏模式及稳定性。To establish an identification method of rock slope failure mode, a cutting slope model was built based on preferred plane theory. Stereographic projection was applied to analyze the relationship between single set of structural planes and cutting slope, and the relationship between multiple sets of structural planes and cutting slope. The stabilities of different situations were compared to identify the failure mode. The result of the proposed criterion and method can reflect failure mode and stability of rock slope under structural control.
