摘　　要：应用混合模型的建模原理,提出了建立空间混合模型的思路和方法,以黄河上游某大型梯级水电站为例,通过建立三维有限元模型,用结构计算方法求出该拱坝各垂线测点的位移值,最后结合有限元模型和空间混合模型,反演了该拱坝典型坝段的弹性模量,为大坝的强度和稳定分析提供依据。反演方法也为其它物理参数的反演提供了有效的思路。In this paper, the idea and the method of establishing space mixed model are brought forward by use of the model building principle firstly and take one of big step flyer hydroelectric station as an example along the upstream of yellow river. Then, every nodes＇ displacement of arch dam is calculated out by using the method of structure calculating through establishing three-dimensional finite element model. Finally, combining the finite element model and space mixed model, the young＇s modulus of arch dam＇s typical monolith which supply the analytic means to appraise the dam＇s strength and stability is inversed. The method of inversing analysis of this article supplies the useful idea to inverse other physical parameters.
