Abstract: For concrete face-slab rock-fill dam (CFRD) constructed on deep alluvium, the stress and deformation properties of dam, foundation, face slab and diaphragm wall were studied by numerical analysis. Furthermore, the interaction of dam foundation and alluvium was analyzed. The study result showed that although the foundation deformation had a significant impact on the stress and deformation of dam, face slab and diaphragm wall, it was still feasible to built high CFRD with its plinth on alluvium foundation.

摘要： 针对深覆盖层上的面板堆石坝，采用数值计算的方法分析了坝体、坝基以及面板和防渗墙的应力变形分布规律，并对坝体与覆盖层的相互作用关系进行了分析论证。分析结果表明，尽管覆盖层地基的变形对坝体、面板和防渗墙的应力变形性状有着明显的影响，但通过采取合理的工程措施，深覆盖层上的面板堆石坝采用垂直防渗处理是可行的。
