摘　　要：将碾压混凝土坝层面的影响概化到整个坝体中,视坝体整体为横观各向同性体,基于实测资料,结合有限元计算,反演坝体横向和竖向弹性模量。然后利用变形等效假定建立横向和竖向弹性模量正分析模型及反演结果,进而推求出层面弹性模量和厚度,为客观模拟层面影响提供了科学依据。This paper generalizes the layer influence of RCC dam into the whole dam body and takes RCC dam as transverse isotropy. Based on the actual measured data and the finite element method, the feedback analysis is used to calculate the transverse and vertical elastic modulus of RCC dam body. And then, based on equivalent deformation assumption, a model is established to analyze equivalent elastic modulus. Applying the model and the results of feedback analysis equivalent elastic modulus, elastic modulus and thickness of RCC dam layer are solved.
