以双溪口面板堆石坝实测沉降监测资料为基础，通过基于免疫遗传算法的位移反分析法对堆石料E-B模型参数进行反演分析，获取了符合工程实际的模型参数。根据反馈分析得到的计算结果，采用邓肯-张弹性非线性E-B模型，分析研究了大坝竣工期及蓄水期的变形及应力分布状态，计算结果表明，大坝蓄水期位移增量较小，面板应力正常，大坝运行安全。

Based on measured settlement data of Shuangxikou CFRD, back analysis on parameters of the E-B model was carried out by means of Immune Genetic Algorithm and the model parameters were obtained in accordance with the engineering practice. According to the calculated results by the back analysis, the deformation and stress distribution of the dam in completion and storage period was studied by the Duncan-Chang elastic nonlinear E-B model. The results showed that, in the storage period, dam displacement increment was less, panel stress was normal, and dam was operating safely.
