某大规模堆积体变形较大，库区左岸上游约1～2km处变形堆积体规模巨大，达3400×104 m3，分布在高程990～1662 m之间，工程区地震基本烈度为Ⅶ度。通过工程地质勘察和历史监测数据分析堆积体的变形机理，采用二维刚体极限平衡法和三维数值差分模型分析评价堆积体的稳定性。

A certain large-scale accumulation mass has relatively large deformation .The deformed accumulation mass located at El.990 –1,662m about 1 –2km upstream on the left bank of the reservoir area is huge in size and its volume reaches 3 ,400 x 104 m3 .The basic seismic intensity of the project region is degree VII .The de-formation mechanism of the accumulation mass was analyzed by engineering geological exploration and study of the historical monitoring data , and the stability of the accumulation mass was analyzed and assessed by the 2-dimen-sional rigid body limit equilibrium method and the 3-dimentioanl numerical finite difference method respectively .
