摘要
苏阿皮蒂水利枢纽建筑物主要包括两岸挡水坝段。发电引水坝段、导流底孔坝段、泄洪底孔坝段、溢流坝段,发电厂房位于左岸发电引水坝段坝后。枢纽布置紧凑合理、结构新颖、技术先进、施工方便,有利于缩短建设工期,节省工程投资。其中,右岸82.5 m高碾压混凝土重力坝坐落于极薄泥质粉砂岩/砂岩水平互层地基、173.55 m宽无闸门控制的溢流坝“台阶+底流”消能布置形式等先进的技术方案,为国内外同类工程之首。
The RCC gravity dam of Souapiti Hydro Project includes retaining dam sections on both sides of the river,power generation diversion dam section,diversion bottom outlet dam section,flood discharge bottom outlet dam section and overflow dam section.The powerhouse is located behind the power generation diversion dam section in the left bank.The overall layout of main structures is compact and reasonable,the structure is also novel and advanced,which is conducive to constructing project,shortening construction period and saving engineering investment.Some technologies are the first of its kind at home and abroad,including constructing the 82.5 m-high RCC gravity dam section in the right bank on extremely thin and horizontal interbedded argillaceous siltstone/sandstone foundation,and adopting“Step+underflow”energy dissipation for the 173.55 m-wide overflow dam without gates.
