【摘要】 合理的滑坡灾害防治工程设计既要考虑滑坡体的稳定性与失稳的危害性，又应考虑防治工程的自身稳定性和安全期限。本文以东大井滑坡为例，依据地面调查、坑槽探及钻探等成果资料，客观地分析和评价滑坡的成因、稳定性与失稳的危害性；并结合三峡工程移民搬迁要求，确定滑坡体及其防治工程的稳定与安全期限，最终制定了合理的防治工程方案。更多还原

【Abstract】 A rational control engineering design of landslide hazard would be thought not only stability and destable harmfulness of landslide, but also stability and safe period of control engineering itself. This paper take Dongdajing Landslide as an example; on the basis of ground survey, pitting, trenching and drilling etc. achievements and materials; analyze and evaluate objectively cause of formation, stability and destable harmfulness of landslide; in the light of demand of the three gorges migration and removal again, determine stable and safe period of landslide and its control engineering; so as to draw up a rational control engineering scheme.更多还原
