摘　　要：着重对反分析原理(包括定义、技术实现手段)进行了论述,并以水电站重力坝为例,应用直接法对弹性结构进行了反分析。为了加强反分析工作的针对性,还探讨了反分析的可辨识性问题。Taking the gravity dam of a hydropower station for example, description is presented on concept of back-analysis (including definitions, technical means for realization) and back-analysis is made on elastic structure with direct method. To strengthen what the back-analysis is aimed at, discussion is also made on the identification of back-analysis.
