This paper mainly introduces some special construction methods in this project through the treatment of high slope of water intake and tailwater tunnel of underground power plant of Guangxi Youjiang Baise Water Conservancy project. In particular, the pressure distributed prestressed anchor cable which is widely used in geotechnical anchoring engineering in China and the vertical wall suspension construction method which is rarely used in actual construction are introduced. It is hoped that through this article, we can play a role in introducing jade to colleagues who do geotechnical anchoring work, and also make a contribution to improving the geotechnical anchoring construction method in our country.
