针对利用软岩料构筑面板堆石坝存在的特殊性问题，根据已有工程的现场和室内试验结果，分析软岩料的级配及强度变形、渗透、流变等工程力学特性，并提出利用软岩料构筑面板堆石坝时应注意几个问题：应以软岩料的现场碾压和渗透试验结果作为设计依据，需高度重视大坝的变形和稳定控制，加强坝体排水设计，高度重视大坝长期强度变形特性对其安全性的影响，在浇筑混凝土面板前应留足坝体预沉降时间，并采取措施防止软岩料进一步风化和遇水崩解。

Concrete-faced rock-fill dams ( CFRDs ) compared with hard rocks the CFRDs with soft rocks have the particularity because of its engineering mechanics properties. According to the field and laboratory experiments of several projects, the particle gradation and the engineering mechanics properties of strength and deformation, the permeability and the creep for soft rock materials were analyzed. Several problems of construction CFRDs with soft rocks were pointed out such as: the dam design should be based on field compaction and permeability experimentation of soft rock materials;special attention should be given to the dam deformation and stabilization control; the drainage of dam body should be reinforced;special attention needs paying to the effect of long-term strength and deformation on dam safety;the appropriate time of dam pre-settlement should be left before constructing concrete face slab; and required controls should also be conducted to prevent the further weathering and water-destruction of soft rocks.
