【摘要】 在对工程反分析与正分析进行比较的基础上，给出反分析的定义。简述了近年来反分析在水利工程中的应用情况，并对反分析方法进行了概括和分类。以土坝渗透系数反分析为实例，结合二维渗流有限元法的ＢＰ神经网络，提出了一种新的水工渗流反分析方法。更多还原

【Abstract】 On the basis of comparing anti-analysis and analysis of water conservancy projects,the definition of anti-analysis is given.The simplified introduction of applying anti-analysis to water conservancy projects of recent years is presented and the summarization and classification of anti-analysis methods are also given.Taking the anti-analysis of earthfill dam permeability coefficient as an example,a new anti-analysis method of hydraulic seepage flow for the BP nervous network of resultant two-dimensional seepage flow finite element method is proposed.更多还原
