【摘要】 某电站大坝为混凝土闸坝,根据水电站工程实际情况,采用非线性D-P本构模型,建立三维有限元模型,采用基于多重响应面的位移正反分析法对影响电站大坝变形的不同参数进行反演分析,并将泄洪闸和表孔闸在正常蓄水位工况、设计工况、校核工况下进行变形及应力分析,参数反演基本合理且参数反演方法正确可行。更多还原

【Abstract】 The dam of a hydropower station is a concrete gate one.In accordance with the actual situation of the station,the non-linear D-P constitutive model is applied to built the 3D finite element model.The inversing analysis is performed for the different parameters,which impact the dam deformation,by application of the analysis method based on deformation of the multiple response planes.Furthermore,analysis on deformation and stress of flood discharge gate and surface outlet gate are carried out.The parameter inversing is rational and its method is correct and feasible.更多还原
