大坝异常性态定性评判的原理及实例分析

Princinle and Case Study for Qualitative Judgement of Abnormal Dam Behaviour

大坝异常性态的定性评判，是从大坝原型监测量中总结出一些变化规律，诸如突变性、趋势性、合理性、相关性、相似性、对称性等，用以对大坝的运行性态进行安全评判。本文概述其基本原理，结合国内外几座大坝实例，进行具体分析研究。

he qualitative judgement of alnormal dam behaviour ie summarized some changelaw,from dam portotype observation quantities. For instance mutation,rationality,correlativi-ty,similarity,tendency,symmetry.etc. Thus,safety judgement was carry out to dam behaviour.Thie paper describes the principle of qualitative judgement and performs analysis inComblination with case studies of several dams at home and abroad.
