摘　　要：邓肯—张E-B模型应用于面板坝的应力应变分析时一般通过室内三轴试验获取模型参数,而中低面板坝一般不进行室内三轴试验,通常采用的工程类比法取得的模型参数计算误差较大,通过基于免疫遗传算法的位移反分析法得到较为符合工程实际的邓肯—张E-B模型参数,并以双溪口水库大坝为例,计算了竣工期沉降量,通过与实测沉降量的对比分析,说明了该方法的合理性。Duncan-Chang E-B model was widely used to analyze the stress and strain of CFRD,and the model parameters generally got through the triaxial test.But low CFRD generally was not performed triaxial test.So,the analysis parameters was usually obtained by using engineering analogy.However,the calculation error of model parameters was larger by this method.E-B model parameters were obtained by back analysis based on immune genetic algorithm,which was in line with the actual project.Taking Shuangxikou reservoir dam for an example,the settlement in time of completion was calculated.By comparing with the measured settlement value,it verified the rationality of the method.
