摘要
白鹤滩坝址地处金沙江干热河谷,是世界第二大装机容量(1600万kW)水电站,工程规模宏大,地质条件复杂,地震、滑坡等灾害频发。针对这一新建特高坝工程,从设计理念、技术方法到效果验证展开分析。通过文献分析与工程案例研究,论述了白鹤滩大坝采用的不对称体型设计、扩底基础、低热水泥混凝土以及智能监测等创新措施。白鹤滩大坝设计安全裕度高,混凝土抗裂安全系数超过2.0,大坝运行中未出现温度裂缝,实现了预期的“无缝大坝”“智能大坝”目标。研究认为,新技术显著增强了大坝的抗震韧性,为超大型水利工程设计提供了有益经验。
The Baihetan Dam site is located in the hot and arid river valley of the Jinsha River,serving as the world's second-largest hydropower station in terms of installed capacity(16 million kW).With its massive engineering scale and complex geological conditions,the site is prone to frequent disasters such as earthquakes and landslides.This study analyzes the design concept,technical methods,and effect verification of this newly constructed ultra-high dam.Through literature analysis and case studies,it discusses innovative measures employed in the Baihetan Dam,including asymmetric structural design,expanded foundation,low-heat cement concrete,and intelligent monitoring.The dam features a high design safety margin,with a concrete cracking safety factor exceeding 2.0,and has achieved the anticipated goals of a"seamless dam"and"intelligent dam"during operation.The research concludes that these new technologies significantly enhance the dam's seismic resilience,providing valuable insights for the design of mega-scale water conservancy projects.
