%X  The additional mass method was applied to detect rockfill density quickly and accurately, and to control the quality of dam filling in-time. Key technologies in the application of additional mass method are elaborated in this paper, including the obtaining of rockfill density through correlation method, the data collection and  processing system, the quality control evaluation system, and the 3-D digitalization. Remote control on the construction quality and digital measurement of the rockfill density were realized by using GPRS to build the data network link between local and remote network. The method was applied to Nuozhadu hydropower station, and good results were achieved.
