大坝结构性态分析评价问题是一个多层次多项目的系统整体分析评价问题，应利用系统分析的观点，将多个观测项目结合起来进行综合分析和评价．在分析了已有综合评价方法的基础上，提出了基于属性识别理论的大坝结构性态综合评价方法．示例表明，这一方法是合理、可行的． The dam structural state analysis and evaluation problem is a multi-level and multi-project system overall analysis and evaluation problem. It should make use of the point of view of system analysis and combine multiple observation items for comprehensive analysis and evaluation. Based on the analysis of the existing comprehensive evaluation methods, a comprehensive evaluation method of dam structural properties based on attribute identification theory is proposed. The example shows that this method is reasonable and feasible.
