摘　　要：变形是拱坝结构性态变化最直观的表征指标,因此通常在拱坝上布置变形监测点,以获取拱坝的变形信息。基于拱坝变形监测数据,充分考虑大坝内部各测点变形之间存在的复杂关联关系,从拱坝结构内部关联及信息融合的角度,提出了确定与待分析测点变形显著线性关联及强非线性关联关系测点的技术,据此构建了利用强关联测点对待分析测点变形进行表征的模型,通过具体工程实例,验证了模型的有效性,为拱坝变形性态分析提供了新的手段。Deformation is the most intuitive indicator of changes in the structural properties of an arch dam.Therefore,a number of deformation monitoring points are usually arranged on the arch dam to obtain the deformation information of the arch dam.Based on the deformation monitoring data of the arch dam,taking into account the complex correlation between the deformations of various measuring points inside the dam,the technology of determining the measuring points with significant linear correlation and strong nonlinear correlation with the deformation of the measuring point to be analyzed is proposed from the perspective of internal correlation and information fusion of the arch dam structure.A model is constructed that uses the strongly correlated measuring points to characterize the deformation of the measuring point to be analyzed.Through specific engineering examples,the effectiveness of the model is verified,providing a new method for the deformation behavior analysis of arch dams.
