空腹拱坝属于超静定结构,由于空腹的存在,其计算域乃是复连通域,结构复杂。坝体拱梁荷载分配与实体拱坝的分析方法有所不同,本文介绍以下几种计算分析方法:(1)用变形协调法计算悬臂梁单位荷载变位求拱梁荷载分配;(2)用有限元法计算拱梁单位荷载变位求拱梁荷载分配;(3)用试验方法确
Fasting arch dam belongs to the statically indeterminate structure. Due to the existence of fasting, the computational domain of the fast arch dam is a complex connective domain with complicated structure. The load distribution of the arch beam of the dam body is different from the analysis method of the solid arch dam. In this paper, the following calculation and analysis methods are introduced: (1) Deformation coordination method is used to calculate the load distribution of the arch beam through the unit load displacement of the cantilever beam; (2) Finite element method to calculate the arch beam unit load displacement and arch beam load distribution; (3) by experimental methods
