摘　　要：以金钟面板堆石坝为算例,用考虑了各向异性做出修正的E-μ模型进行计算.该模型考虑了蓄水期的主应力偏转问题,对不同加荷方向取不同的弹性模量和泊松比,与E-B模型相比其结果更为合理.Take Jinzhong faced rockfill dam as an example,the modified Duncan E-μ model in consideration of anisotropy is used for calculation.In this model,it solves the problem of rotation of the principal stress,the Young s modulus and Poisson s ratio is different at the different loading direction.And then,the results are analyzed and compared with that gotten by Duncan E-B model.
