摘要
Abstract
On May 12,2020,the F46/F21 fault at the exit of a flood discharge tunnel of a hydropower station caused slope collapse.The collapse height was about 40 m,and the collapse volume was about 11000 m3,which seriously restricted the realization of diversion target by the end of December 2020.All the parties in-volved in the construction have formulated the treatment plan of the collapse slope,adopted the combined treat-ment measures such as backpressure stone slag,sprayed steel fiber concrete,I-beam scaffolding and corbel col-umn composite support structure,steel anchor pier temporary support,pipe shed and so on,and completed the slope treatment quickly and safely under extremely difficult conditions,and realized the target of diversion of Batang Hydropower Station by the end of December 2020.关键词
