Abstract First the concept of anisotropic soft rock in concrete face rockfill dam construction(CFRD) is put forward，and it is different from hard and soft rocks in traditional sense. By studying the anisotropy of soft rock(schist stone for example)，and its derivatives heap chlorite，the physico-mechanical properties of anisotropic soft rock were given in the paper. On the basis of partition map of hard rock，sand and gravel dam，primary partition map of anisotropic soft rock dam and associated construction measures have been proposed. Taking a hydropower station CFRD project in Xinjiang，for example，combined with the special topographic and geologic conditions，a 3D model for the standard cross-section with three kinds of partition was built. Also numerical simulation based on nonlinear finite element method(FEM) was done. The results were analyzed and compared，and the recommended solutions were given to make full use of local anisotropic soft rock.
