摘　　要：面板堆石坝碾压施工中,堆石体密度传统的坑测法已远不能满足堆石坝现代施工进度和质量控制的要求,为了保证大坝的填筑质量,对堆石体快速的无损干密度测试技术的研究显得十分必要。文章论述了附加质量法和瑞雷波法对堆石体干密度检测的方法与特点,研究结果证明,这二种方法均能满足堆石坝体高强度填筑施工质量控制的要求。In construction of face rockfill dams, the pit checking method, that was traditional one for checking density of rockfill body, can not meet the requirement of modern construction schedule and quality control of those dams. In order to ensure the filling quality of rockfill body, it is necessary to research quick, harmless checking technology for its dry density. The paper has discussed methodology and features of two checking methods for dry density of rockfill body, the added mass one and Reyleigh wave one. The results of researching have proved that the both of methods can meet the requirement of construction quality control of filling with high intensity.
