摘　　要：在大量地质背景资料的基础上，利用ＣＯＳＭＯＳ／Ｍ大型工程有限元软件，作为非线性问题，按大变形大位移情况对长江三峡库区巴东县城新址黄土坡滑体的稳态进行初步分析，跟踪应力—应变及位移的分布与变化，进而对滑体整体稳定安全系数。Based on a vast amount of geological setting data, applying COSMOS/M, a finite-element analysis software for large engineering, the stable state of Huangtupo sliding mass in Badong county has been analysed as a nonlinear deformation under the circumstance of large deformation and displacement. Meanwhile, the distribution and variation of the stress-strain and displacement in the sliding mass have been monitored. Finally, the author has reached some worthy conclusions on satety coefficient of the sliding mass stability, possible damage pattern, etc.
