摘要
堆积体结构空间若层面分隔,容易崩塌,对水电站工程建设造成严重阻碍,可采取预应力锚索抗滑桩施工技术,加固堆积体。文章简要阐述了堆积体预应力锚索抗滑桩技术原理,并以白鹤滩水电站工程为例,结合工程地质条件确定设计方案、施工方案,提出施工技术应用措施。结果表明,该工程采取预应力锚索抗滑桩技术,竖向位移、地表沉降均在允许范围内,符合工程要求。
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.
