某混凝土高拱坝整体安全度评估OA北大核心CSTPCD
Evaluation on Overall Safety Degree of a High Arch Dam
某混凝土双曲拱坝坝型和地质条件较为复杂,需要开展拱坝结构特性研究,为此,就拱坝在基本荷载组合和特殊荷载组合下的应力、稳定状态、影响坝体应力变形状态因素的敏感性和拱坝的超载安全度等进行分析,并采用三维非线性有限元超载法对拱坝-地基系统的整体安全性进行研究,确定了系统的整体超载安全度.
As the complex geological conditions and dam shape, the structural characteristics o￡ a double-curvature arch dam needs to be studied. Thus, the stress, stability, sensitivity of factors which affecting stress and deformation state, and safety overload of the dam are analyzed under the action of basic load combinations and special load combinations. The overall safety of dam-foundation system is also studied by the three-dimensional nonlinear finite el…查看全部>>
