针对岩质高边坡的滑坡失稳的典型破坏形式,采用非连续变形分析(DDA)这一数值分析方法,结合某高速公路岩质高边坡工程实例,建立计算模型,深入研究边坡岩体的结构面参数与边坡变形的相互关系,分析不同工况下边坡块体的极限内摩擦角和稳定安全系数,进而评价边坡的稳定性,结果表明与边坡稳定实际情况基本吻合.%According to the classical damage problem of high rock slope,by use of DDA,the discontinuous deformation analysis ( DDA) model is set up,combined with a rock edge slope engineering case of the highway. The relationship between joint parameters and slope deformation is studied,and the limited internal friction angle of the sliding face of slope is obtained under some conditions,the safety factor of slope stability is calculated, and the slope stability is evaluated. Ttie results show that the actual situation with the basic agreement.
