我国混凝土面板堆石坝的发展与经验

Development and experience of concrete face rockfill dam in China

我国混凝土面板堆石坝建设经过１０ 多年的发展， 取得了丰硕的成果， 到１９９８ 年底， 已建成４２ 座， 在建３２ 座， 待建的更多。目前无论在数量上还是规模上都居世界前列， 在技术上也有所创新和改进， 主要表现在对地形地质条件的适应性、枢纽布置考虑土石方平衡、泄洪建筑物布置、坝体分区和筑坝材料应用、面板混凝土、接缝止水结构和材料、施工导流与渡汛等方面。

The construction of the concrete face rockfill dam in China has gained plentiful achievements after the development for more than 10 years. Up to the end of 1998, 42 concrete face rockfill dams were completed, 32 such dams under construction and many such dams planned. At present, the construction of concrete face rockfill dam in China, in both its amount and its scale, stands in the forefront of that in the world. Some innovations and improvements also have been made in the technology, such as the adaptability to the geographical and geological conditions, earth rock volume balance in the general project layout, flood releasing structure layout, dam body zoning and construction material application, facing concrete, joint sealing structure and its materials, construction diversion, safety during flood season, etc.
