摘　　要：倾倒变形是中陡倾角岩质边坡中常见的一种破坏型式,结合玛尔水电站工程实例对倾倒变形体边坡的结构特征、变形破坏机制进行分析论证,并对变形体在蓄水前后不同工况、不同运行期的稳定性进行深入地分析、计算和评价,结果表明不同工况、不同运行期倾倒变形体边坡稳定性差别较大。The toppling deformation is a common type of failure pattern in the steep dip rocky slope.The paper analyzes the deformation mechanism of the combination of Martha hydropower station project on the toppling deformation slope structure.Analysis,calculation and evaluation of the deformation in different stability conditions and different operation period before and after impoundment have been carried out.The results show that the slope stability of the deformable body in different operating conditions and operating period is different.
