【摘要】 采用块体极限平衡Sarma法和平面非线性有限单元法对小浪底水利枢纽东苗家滑坡体稳定性进行了分析研究,较客观地反映受多种条件制约的复杂岩质边坡的稳定性问题,提出相应的合理的处理方案。综合计算成果分析,东苗家滑坡体在自然状态下处于基本稳定状态,整体安全系数接近于1.0,若考虑Ⅶ度地震,根据Sarma法和有限元计算结果,安全系数分别为0. 73和0.84,处于不稳定状态。更多还原

【Abstract】 Dongmiaojia landslide is complex and large rock slope located about 2 km down stream of the dam site of Xiaolangdi Project on Yellow river,on the left bank.The slope stability is analyzed by means of Sarma method and finite element method.The landslide is stable in natural state and unstable during earthquake when seismicintensity is more than 7 based on the methods.Stability analytical and computational methods are proposed for complex rock slopes.更多还原
