Back analysis of Tongtou arch dam with multiparameters based on mixed model

YANG Qiang,FU Deyu,XUE Lijun(State Key Laboratory of Hydroscience and Engineering,Tsinghua University,Beijing 100084)  
This paper introduces the back analysis of Tongtou arch dam with multiparameters by using the mixed model of observational displacement regression.In the analysis process,the simplified single variable arithmetic is used for optimized back analysis on the multi-parameters.The optimized target function is used to examine the credibility of the analyzed parameters for the conditions of smaller variation of water level,and a set of integrated anti-analysis process is formed.
