摘　　要：混凝土坝的变形监测信息源复杂、多样,变形监测信息不可避免地存在不完整问题,对变形性态的分析造成困难.本文将混凝土坝变形信息的不完整问题划分为单值缺失问题和连续多值缺失问题来处理,针对性地提出了基于非局部平均思想的单值缺失估计方法和基于空间邻近点BP映射的多值缺失估计方法,并由工程实例验证了两种方法的有效性.The deformation monitoring information source of the concrete dam is complex and varied, so that the deformation monitoring information inevitably has incomplete problem, which makes it difficult to analyze the deformation state. In this paper, the incomplete problem of concrete dam deformation information is divided into single value missing problem and continuous multi value missing problem to deal with. The single value missing estimation method based on the non local mean idea and the multi value missing estimation method based on the spatial neighborhood point BP mapping are proposed, and the effectiveness of the two methods is verified by the engineering example.
