摘　　要：针对三江水库地质条件复杂和大坝填筑料多样等特点,采用非线性模型对大坝施工期和运行期进行三维仿真分析,并对堆石体主要参数进行敏感性计算分析。结果表明,三江大坝结构设计合理,坝体应力和变形、面板挠度和应力、接缝变形等分布符合一般规律。In view of complex geological conditions of Sanjiang Reservoir and the diversity of dam filling material, three-dimensional simulation of dam during the construction and operation period is analyzed by using nonlinear model. And then the sensitivity analysis of main parameters of rockfill body is carried out. The results show that the structure design of Sanjiang dam is reasonable; the dam deformation and stress, the deflection and stress and deformation of joint distribution accord with the general rules.
