摘要
白鹤滩坝址两岸地形地质条件不对称,坝基中下部出露特殊的柱状节理玄武岩,断层、层间层内错动带发育,岸坡卸荷发育强,坝址地震烈度高。针对复杂的工程地质条件和高标准建设要求,白鹤滩拱坝设计研究围绕坝址坝线选择、不对称拱坝、坝基处理、建基面防松弛变形、高坝抗震、坝体温控防裂等关键技术难题,开展了大量的专题研究及技术攻关,取得了丰硕的成果,保障了工程顺利建设。
Baihetan dam site is featured with asymmetry of topographic and geological condition,special columnar jointed basalt,development of fault and interlayer dislocation zones,strong development of bank slope unloading and high seismic intensity.In consideration of geological conditions and high standard of construction,the design of Baihetan Arch Dam put an emphasis on key technologies of dam site and dam line selection,as well as asymmetry arch dam,anti-slack deformation of foundation surface,high dam earthquake resistance,dam body temperature control and crack prevention.Owing to a great number of special subject studies,fruitful results has been generated that have ensure smooth construction of the project.
