【摘要】 巴贡水电站位于马来西亚沙捞越州中部拉让江支流巴鲁伊河上。大坝为混凝土面板堆石坝,坝顶高程为235.00 m,最大坝高202 m,是目前已建和在建的200 m级以上面板堆石坝之一。坝高库大,填筑材料主要由杂砂岩和部分页岩(泥岩)组成,坝体变形尤其是后期变形,坝体材料分区、压实标准及变形控制,适应坝体变形的止水结构,面板设计,大坝填筑施工期间雨季时段长,降雨量大,解决大坝施工期反渗排水问题等是设计工作中的重点和难点。已有的监测成果表明:在巴贡面板堆石坝的设计、施工中所采用的技术是合适的。更多还原

【Abstract】 Bakun hydropower station is located on the Balui River in the middle of Sarawak,Malaysia.Bakun dam is a CFRD with crest elevation of 235.00 m,maximum height of 202 m,one of the highest CFRDs built or under construction in the world.With a large reservoir,the high dam is mainly filled by greywacke and some shales(mudstones).The design emphasis and difficulties involve dam deformation especially later deformation,zoning of dam materials,compaction standards and deformation control,the sealing structure adaptable to dam deformation,face slab design,long rainy season and large rainfall during dam filling,addressing of anti-seepage and drainage during dam construction,etc.The available observation results show that the technologies applied in Bakun CFRD design and construction are applicable.更多还原
