摘　　要：介绍云南省云鹏水电站心墙堆石坝的主要设计特点,根据实际料源情况有针对性地对坝体结构进行了几次优化调整,通过坝体体型的调整、坝后排水棱体的设置、不同料源按区域混合上坝等措施,最大程度利用了现场开挖料,加快了施工工期,为业主创造了较大的经济效益。多年运行的监测数据表明,坝体变形、应力、渗流等均已稳定,且处于较为合理的范围。This paper introduces the main design features of the core rockfill dam of Yunpeng Hydropower Station in Yunnan Province.The structure of the dam body has been optimized several times according to the actual material source.By means of adjustment of dam body type,setting of drainage prism behind dam and mixing different material sources into dam according to region,excavated materials on site are utilized to the maximum extent,construction period is speeded up and great economic benefit is created for the owner.The monitoring data for many years of operation shows that the deformation,stress,and seepage of dam body are all stable and in a relatively reasonable range.
