摘　　要：应用非线性有限元法对三峡库区白沙坡崩滑体在多种工况下的稳定性进行了计算。结果表明,三峡库区白沙坡崩滑体在天然重力、天然重力+135m回水水位和天然重力+175m回水水位3种工况下是稳定的,而在天然重力+175m回水水位+地震(按地震烈度6度考虑)工况下处于不稳定状态。这为该崩滑体防治决策提供了依据。The slump-mass stability of Baishapo in the Three Gorge reservoir area was calculated under mare load composes by nonlinear finite element method. The results showed that the Baishapo slump-mass in the Three Gorge reservoir area was stable under the three load composes of the natural gravitation, the natural gravitation ＋ 135 m water level and the natural gravitation ＋ 175 m water level. But it was unstable under the load composes of the natural gravitation ＋ 175 m water level ＋ earthquake （by the account of No.6 grade intensity）. This result provided the basis for the treatment decision of the slumpmass
