摘要
近些年来,对有条件的现有水库大坝进行加高扩建是满足日益增长用水、用电需求的经济可行的方法。混凝土坝具有易施工、可靠性强、对工程现状影响较小等特点,因此国内外目前对水库加高多针对混凝土坝开展。本文从国内混凝土坝加高需求出发,在系统收集国内外混凝土坝加高案例的基础上,总结了混凝土坝的加高原因和加高方法,分析了混凝土坝加高过程中存在的主要问题及解决方案,对混凝土坝加高技术进行了总结和展望,可为混凝土坝加高工程设计和施工提供借鉴。
In recent years,the economic feasibility of extending and raising the height of existing dams for reservoirs with favorable conditions has become a practical method to meet the increasing demands for water and electricity.Concrete dams are preferred for such heightening projects due to their advantages of ease of construction,high reliability,and minimal impact on the existing infrastructure.Consequently,both domestically and internationally,the focus has been on raising the height of concrete dams for reservoirs.This paper starts by examining the domestic demand for raising the height of concrete dams and,based on a comprehensive collection of domestic and international case studies on concrete dam heightening,summarizes the reasons and methods for raising the height of concrete dams.It also analyzes the major challenges encountered during the heightening process and provides solutions.The paper concludes with a summary and outlook on the technology for raising the height of concrete dams,aiming to serve as a reference for the design and construction of concrete dam heightening projects.
