摘　　要：主要介绍了老挝南椰Ⅱ水电站粘土心墙土石坝坝基及坝料设计,针对坝基全风化覆盖较深,变形较大的特点及工程经济性。大坝部分基础坐落于全风化基岩,坝体大部分采用全风化料填筑,通过大量的试验资料与计算分析,方案是可行的,工程是经济的。The paper gives an introduction to the design of dam foundation and dam materials of the clay core earth-rock dam of Nanye-Ⅱ hydropower project in Laos. In view of wholly weathered overburden and deformation being deep and large in the foundation for the dam respectively and in view of economy of the project, most of the foundation for the dam is placed on the wholly weathered bed rock and most of the dam body is of wholly weathered material. The test and analysis results have proved the project feasible and economical.
