摘要
小湾水电站混凝土双曲拱坝是即将建成的世界最高拱坝,许多技术难题位居世界第一,工程建设极具挑战性。结合对关键技术的研究实践与认识,介绍了建设中遇到并成功攻克的700m高工程边坡处理、饮水沟堆积体蠕滑变形治理、坝基岩体开挖卸荷松驰、拱坝混凝土温控防裂等主要技术难题。
The double-curvature concrete arch dam of Xiaowan Hydropower Station is the highest arch dam in the world to be completed soon. The construction of the dam encountered many unprecedented technical difficulties and is thus quite challenging. Combining the research, practices and knowledge of key technologies, this paper introduces main technical problems encountered and successfully conquered during the construction of the Project, such as 700m high slope treatment, creep deformation treatment of Yinshuigou accumulation body, unloaded looseness of rock mass of dam foundation due to excavation, and the temperature control and anti-cracking of concrete of arch dam.
