三道白河水电站沥青心墙堆石坝防渗结构研究与分析

Study on Impervious Core Wall Structure of Rockfill Dam for Water Power Station at the Sandao White River

对七十年代初吉林省三道白河水电站堆石坝中采用沥青渣油混凝土防渗心墙结构工程，为我国北部高寒地区利用大庆油田副产品——渣油作为防渗材料使用的初步尝试。经多年的运行检测表明，此工程防渗结构无论在变形和渗漏方面均满足工程的使用要求，实属北方高寒地区采用沥青渣油混凝土防渗结构的成功实例。

Impervious bitumen residuum concrete core wall structure of rockfill dam for water power station at the Sandao White River, Jilin province, built in the early 1970s is a initial practice using residual oil, by product of the Daqing oil field, as impervious material in severe cold region. Checking its operation for many years proves that the project meets demands of service for deformation and impermeability. It is a successful engineering example using impervious structure of bitumen residuum concrete in severe cold region. The author of this paper suggests that this technology should be used widely.
