预应力锚索在漫湾水电站左岸边坡加固处理中,实施面之广、数量之多,在我国水电建设史上尚属首例。按设计方案,左岸边坡加固处理是以锚固桩(洞)为主,1989年3月才引进预应力锚索技术,至1990年8月底,整个左岸边坡共实施锚索1336根,其中,1000kN级的有1074根,1600kN级的20根,3000kN级的232根,总锚固力为1800MN,约站整个左岸边 Prestressed anchor cable reinforcement in the left bank of Manwan Hydropower Station, the implementation of a wide range, as many as the first case in the history of hydropower construction in China. According to the design scheme, the reinforcement of the left bank slope is anchored piles (holes), and the prestressed anchor cable technology was introduced only in March 1989. By the end of August 1990, a total of 1,336 anchor cables were implemented throughout the left bank slope, 1000kN grade 1074, 1600kN grade 20, 3000kN grade 232, the total anchoring force of 1800MN, about the entire station left bank
