天荒坪抽水蓄能电站上库是我国第一个采用沥青混凝土护面全库防渗并由外国承包商采用现代化机械设备施工的工程 ;护面采用简式结构。沥青混凝土具有适应变形能力强、柔性好、防渗性能优越、易于维修等特点 ,其在天荒坪电站上库护面施工过程中的成功应用 ,积累了结构设计、材料配比、施工工艺、质量控制等方面的经验 ,将对水工沥青混凝土在我国的推广应用产生积极影响。
Tianhuangping pumped storage power plant on the library is China’s first use of asphalt concrete retaining the whole reservoir seepage by the foreign contractors to adopt modern machinery and equipment construction works; face using simple structure. Asphalt concrete has the characteristics of strong adaptability to deformation, good flexibility, excellent impermeability and easy maintenance. The asphalt concrete has been successfully applied in the construction of the surface protection of the Tianhuangping Hydropower Station, accumulating structural design, material ratio, construction technology, Quality control and other aspects of experience, hydraulic asphalt concrete in China will have a positive impact on the promotion and application.
