摘　　要：为控制老挝Nam Khan 2面板堆石坝工程投资,在详细设计阶段通过抬高趾板基础崁深、采用斜趾板结构、调整趾板内坡开挖的三项优化措施,减少了石方开挖约30万m^3,为大坝节省了上千万投资,对工程投资和工期的控制起到了重要作用。In order to control the investment of Nam Khan 2 concrete faced rockfill dam in Laos,In the detailed design stage,three optimization measures were adopted,such as raising the foundation of the toe plate embedded deep,using the inclined toe plate structure,and adjusting the excavation of the inner slope of the toe plate,which reduced the rock excavation by about 300,000 m^3,saved tens of millions of investment for the dam and played an important role in the project investment and period control.
