The spatial layers within a debris structure are prone to separation,leading to collapses that pose significant obstacles to the construction of hydropower projects.To reinforce the debris structure,pre-stressed anchor cable anti-slide pile construction technology can be employed.This paper briefly explains the principles of pre-stressed anchor cable anti-slide pile technology and applies the Baihetan Hydropower Station Project as a case study.It discusses how the design and construction plans were determined based on the engineering geological conditions and proposes application measures for the construction technology.The results indicate that the use of pre-stressed anchor cable anti-slide pile technology in this project kept vertical displacement and surface subsidence within permissible limits,meeting the engineering requirements.
